Stop the UI before a silent Windows update and suppress the installer reboot
On silent MSI updates msiexec could reboot the machine on its own. The running UI holds a lock on its own exe, and since msiexec runs as LocalSystem it cannot close the interactive user's UI via Restart Manager, so the MSI scheduled the
file replacement for the next reboot and marked the install restart-required.
Terminate netbird-ui.exe before launching the installer and wait until its image file is released; the existing deferred restart brings it back after the install on every exit path
Run msiexec with /norestart REBOOT=ReallySuppress so it never reboots on its own
Treat exit codes 3010/1641 as success with a warning instead of a failure

Auto-update logic moved out of the UI into a dedicated updatemanager.Manager service that runs in the connection layer. The
UI no longer polls or checks for updates independently.
The update manager supports three modes driven by the management server's auto-update policy:
No policy set by mgm: checks GitHub for the latest version and notifies the user (previous behavior, now centralized)
mgm enforces update: the "About" menu triggers installation directly instead of just downloading the file — user still initiates the action
mgm forces update: installation proceeds automatically without user interaction
updateManager lifecycle is now owned by daemon, giving the daemon server direct control via a new TriggerUpdate RPC
Introduces EngineServices struct to group external service dependencies passed to NewEngine, reducing its argument count from 11 to 4
