Merge main into ui-refactor; port MDM support to the Wails UI

Integrates main's MDM configuration-profile feature and adapts it to the
Wails UI (this branch had already replaced the Fyne UI).

Conflict resolution:
- go.mod/go.sum: take main's deps; howett.net/plist pinned to v1.0.2-... (tidy)
- client/proto/daemon.pb.go: regenerated from the merged daemon.proto
- client/internal/peer/status.go: union of ipToKey (main) + sessionExpiresAt (HEAD)
- client/server/server.go: main's intent/liveness model (connectionGoroutineRunning,
  clientRunning no longer cleared by the goroutine) + empty-PSK guard
- client/ui/client_ui.go, client/ui/profile.go: removed (dead Fyne UI)

MDM port (backend + tray):
- services/settings.go: expose MDMManagedFields plus a managedFields map keyed
  by Config field names so the settings form can gate a control without
  translating mdm.Key* names
- tray: gate Profiles / Exit Node menus on DisableProfiles / DisableNetworks via
  GetFeatures, refreshed on the config_changed system event (replaces the legacy
  2s poll); localized MDM policy-applied toast in all shipped locales
- client/proto/metadata.go: shared constants for the config_changed /
  policy_applied event markers

PreSharedKey: GetConfig now returns preSharedKeySet (bool) instead of the masked
value; the settings form provides its own placeholder and sends a new key only
when the user types one.

+    NetBird MDM preferences (macOS) — bare plist for MDM platforms that
+    accept a managed-preferences plist tied to a bundle identifier
+    (e.g. JumpCloud "Mac Application Custom Settings", Mosyle "Custom
+    Settings", Jamf "Application & Custom Settings" → External
+    Application).
+
+    Bundle identifier (preference domain): io.netbird.client
+
+    The MDM provider will wrap this plist into a Configuration Profile
+    payload of type com.apple.ManagedClient.preferences and push it to
+    target devices via the Apple MDM protocol. The OS materializes the
+    final file at:
+        /Library/Managed Preferences/io.netbird.client.plist
+    which is what the NetBird daemon's client/mdm/policy_darwin.go
+    loader reads on every 1-minute MDM reload tick.
+
+    For MDM platforms that expect a full Configuration Profile instead
+    of a bare plist (Custom Configuration Profile / .mobileconfig upload),
+    use docs/netbird-macos.mobileconfig — same keys, additional Payload*
+    envelope.
+
+    Editing this file:
+      - Remove or comment out any key you do NOT want to enforce. The
+        daemon treats an absent key as "no enforcement" for that field.
+      - Keep the document well-formed XML. Validate locally with:
+            plutil -lint docs/io.netbird.client.plist
+      - Keys are camelCase; values are typed (<string>, <true/>, <false/>,
+        <integer>). See docs/src/pages/client/mdm-integration.mdx (the
+        public docs page) for the full reference.
+
+    Persistence caveat:
+      macOS wipes /Library/Managed Preferences/ at every boot on
+      devices that are NOT MDM-enrolled. This plist only sticks across
+      reboots when delivered through a real MDM channel. For local
+      testing on an un-enrolled host, write the file manually as root
+      and accept it will not survive the next boot.

+
+    Read at runtime by the netbird daemon's macOS loader

+    Bundle identifier: io.netbird.client
+        (confirm against the signed pkg before fleet roll-out)
+
+    Distribution:
+      - sign with `productsign --sign "Developer ID Installer: ..." ...`
+        before fleet roll-out (Apple-Configurator-2 won't install an
+        unsigned profile on Sonoma+ without user override).
+      - For local dev install: `sudo profiles install -path netbird-macos.mobileconfig`.
+      - For MDM (Jamf/Kandji/Mosyle/Intune): upload as a Custom Profile.
+
+    Editing:
+      - Replace UUID placeholders below with fresh UUIDs (`uuidgen` on
+        macOS) when forking this template for a real fleet — each
+        deployment should have unique UUIDs so the OS treats it as a
+        distinct profile.
+      - Tune the PayloadContent values to the policy you want to enforce.
+      - Remove any key you do NOT want to enforce (the daemon treats an
+        absent key as "no enforcement" for that field).
+
+    iOS note:
+      This file is macOS-specific. iOS uses managed app config via
+      UserDefaults[com.apple.configuration.managed] under a different
+      payload type (com.apple.app.configuration.managed); the wrapper
+      structure is the same but the inner payload dictionary differs.

+#
+# SYNOPSIS
+#   Push the NetBird MDM policy to a macOS device via JumpCloud Commands.
+#
+# DESCRIPTION
+#   This is the macOS counterpart of docs/netbird-policy.reg.ps1.
+#   It writes the values declared in the "POLICY VALUES" block below to
+#   the managed-preferences plist that the NetBird daemon's
+#   client/mdm/policy_darwin.go loader reads on every 1-minute MDM
+#   reload tick:
+#
+#       /Library/Managed Preferences/io.netbird.client.plist
+#
+#   Once the plist lands, the daemon picks up the new values without
+#   restart (the ticker calls Config.apply() → applyMDMPolicy() and
+#   restarts the engine on diff).
+#
+# DEPLOYMENT (JumpCloud)
+#   1. Admin Console -> Device Management -> Commands -> +.
+#   2. Type: Mac, Shell, Run as: root.
+#   3. Paste this file verbatim into the command body.
+#   4. Bind to the target system group, save, run.
+#
+# IMPORTANT: PERSISTENCE
+#   macOS wipes /Library/Managed Preferences/ at every boot on devices
+#   that are NOT MDM-enrolled. For a persistent fleet rollout, push the
+#   companion docs/netbird-macos.mobileconfig as a Custom Configuration
+#   Profile (Admin Console -> MDM -> Mac Custom Configuration Profiles)
+#   instead of this script. Use this script when:
+#     - the device is MDM-enrolled (file survives reboots), or
+#     - you need a one-shot test push before reboot, or
+#     - you orchestrate via JumpCloud Commands and want the same
+#       variable-driven workflow as the Windows .ps1 sibling.
+#
+# IDEMPOTENCY: re-running with the same values is a no-op from the
+# daemon's point of view (the 1-minute reload ticker diff returns empty).
+#
+# SECURITY: PreSharedKey is redacted in this script's log output.

+<#
+.SYNOPSIS
+  Push the NetBird MDM policy to a Windows device via JumpCloud Commands
+  by importing a sidecar netbird-policy.reg file.
+
+.DESCRIPTION
+  Windows counterpart of docs/netbird-macos.sh. Outcome:
+  HKLM\Software\Policies\NetBird populated from the attached
+  netbird-policy.reg file, daemon picks up the change via the
+  1-minute MDM reload ticker.
+
+  Deployment:
+    1. Admin Console -> Device Management -> Commands -> +.
+    2. Type: Windows PowerShell. Run as: SYSTEM.
+    3. Paste this file verbatim into the command body.
+    4. In the same command, attach `netbird-policy.reg` as a file.
+       JumpCloud copies attached files into the command's working
+       directory before invoking the script, so `$PSScriptRoot` or
+       Get-Location resolves to where the .reg lives.
+    5. Bind to the target system group, save, run.
+
+  Producing the .reg file:
+    On a reference machine, after configuring the policy values either
+    via gpedit (GPO) or manual `reg add`, export with:
+
+        reg export "HKLM\Software\Policies\NetBird" netbird-policy.reg /y
+
+    Then attach the resulting file to the JumpCloud command.
+
+  Semantics:
+    - The script nukes the existing HKLM\Software\Policies\NetBird key
+      before importing the .reg, so the .reg is the SINGLE SOURCE OF
+      TRUTH. Any value present in the registry but absent from the .reg
+      is removed. This is what an MDM admin almost always wants.
+    - Setting the .reg to an empty (header-only) file effectively unsets
+      the policy.
+
+  Idempotency: re-running the script with the same .reg is a no-op from
+  the daemon's perspective (values identical → 1-min ticker sees no
+  diff → engine not restarted).
+
+  Exit codes: 0 = success; 1 = .reg missing or reg.exe error.
