At proxy connect time, the declared cluster address is validated for
shape and checked for availability (`IsClusterAddressAvailable`), and
from then on the declaration is what routes the cluster's mappings to
the connection. Deployments that embed management through the
integrations seam may need a policy on that claim — deciding which
credential is allowed to declare which address.
This adds an optional `ProxyConnectAuthorizer` hook on
`ProxyServiceServer`, following the pattern of the existing `Set*` seams
(`SetServiceManager`, `SetAgentNetworkSynthesizer`,
`SetAgentNetworkLimitsService`, `SetProxyController`):
- A nil-able interface field plus `SetProxyConnectAuthorizer`, guarded
by the existing mutex.
- One call at the end of `validateProxyConnect`, so both
`GetMappingUpdate` and `SyncMappings` are covered by a single site.
- **Nothing installs it by default** — with the hook unset (always, in
this repo), behavior is byte-for-byte unchanged, which the tests pin.
Design details:
- The authorizer runs **last** — after input validation and the
availability check — and **outside** the account-scoped branch, so
management-wide tokens and token-less connects are also presented to it
rather than bypassing policy.
- The authorizer receives the presented `*types.ProxyAccessToken` (nil
when none), the proxy ID, and the declared address. Everything it needs
is already in the request/context; no proto or schema change.
- A plain error from the authorizer surfaces as `PermissionDenied`,
keeping an authorization rejection distinguishable from the
`AlreadyExists` used for address conflicts in proxy logs. A status error
passes through unchanged so implementations can pick their own code.
Store the per-account gateway endpoint as {domain, proxy_address} with a
global unique index on the full hostname; dedicated = (domain ==
proxy_address). Bootstrap becomes an explicit POST carrying exactly one
of proxy_address (server allocates an adjective-noun label beneath it)
or endpoint (claimed verbatim, address-first); provider create loses its
bootstrap side effect. PUT is a full replace with every field required —
the immutable identity fields must be echoed unchanged and a mismatch is
rejected with 422. A guarded DELETE releases the endpoint: refused with
412 while providers exist or a proxy is actively serving the endpoint
hostname (matched case-insensitively); re-creating bootstraps fresh. A
self-addressed pin excludes its address from the account's cluster allow
list, and the live mapping update path now addresses the serving proxy
from the synthesized service. Existing rows are migrated on all three
store engines.
## Describe your changes
The native_webview2loader build tag embedded Microsoft's
WebView2Loader.dll via //go:embed. Those DLLs are gitignored in the fork
and go mod vendor resolves embed patterns regardless of build
constraints, so vendoring the module failed on the missing files when
packaging for openSUSE.
The fork now removes that branch along with the go-winloader dependency,
which drops out of the module graph here. The default GoWebView2Loader
path is unaffected.

## Describe your changes
The UI shells out to xdg-open to launch the external browser for the SSO
verification page, which the embedded webview cannot open inline, and to
reveal the debug bundle in the file manager.
client/ui/build/linux/nfpm/nfpm.yaml lists xdg-utils for every package
format, but the released packages are built from the goreleaser configs,
where it was missing: the GTK and WebKitGTK dependencies carried over
and xdg-utils did not. Add it to all four nfpm dependency lists.

A user in the Pending Approval state could complete SSO and reach any
SSO-protected reverse proxy service distributed to a group they belong
to, including the All Users group. The reverse proxy authorization path
checked the session token signature, that the user exists, that the
user's account matches the service's account, and group membership —
never the user's account status. The REST API (`permissions/manager.go`)
and peer registration both gate on that state, but the proxy gRPC
service does not go through the permissions manager, so neither gate
applied. A pending user is persisted as blocked and pending approval, so
blocked users reached those services the same way.
`ValidateSession` now denies on account status, reporting
`pending_approval` or `user_blocked` so the proxy access log and the
denied page carry the cause rather than a generic refusal.
`GenerateSessionToken` refuses to mint a token for such a user at all,
so the browser never receives a session cookie and the OIDC callback can
tell the user why instead of showing "Service configuration error".
`ValidateUserGroupAccess` and `ValidateTunnelPeer` close the same gap;
for the tunnel path this covers a user blocked after their peer was
registered, since peer group membership alone kept mesh-origin access
open.
A single helper produces both the denied reason for the RPC responses
and the sentinel error for the error-returning callers, so the four
entry points cannot drift apart. A user the store cannot resolve is
denied rather than passed through.
One thing deliberately left out: session cookies are validated locally
by the proxy against the service public key with no management
round-trip, so a cookie issued before a user is blocked stays valid
until it expires (24h by default). That is a revocation-propagation
problem rather than this authorization gap, and every option for it
(per-request validation with a cache, short-lived tokens with refresh,
push-based revocation) changes the proxy hot path or the
proxy/management protocol. Worth its own ticket.
