test(connect): phase 5 — restart lands on the selected profile, no login (#827)

* test(connect): pin restart-with-scoped-profile token resolution (phase 5)

* fix(profiles): scope switch via un-clamped active-profile state

The switch persisted the server profile through serverStore.selectedProfileId,
whose selfHealed() clamps ids absent from the local connection list — server
profiles like "meow" never exist there, so the scope silently reset to
default and the re-dialed socket created the fresh session in the wrong
profile (live logcat 2026-08-06: session.create carried profile=default
right after switching to meow).

- AuthManager: prefs-backed activeProfileId state, immune to the clamp,
  restored on startup; resetAuthStateForTest clears it
- ProfileScopeInterceptor + WsProfileParams + ChatViewModel fetchContextUsage:
  read the active profile instead of the connection selection
- ProfileSwitchCoordinator: write activeProfileId; dial the socket on
  Dispatchers.IO (the ticket mint did blocking I/O on the main thread —
  NetworkOnMainThreadException — and fell back to a 1s reconnect)
- ProfilesViewModel: inject the IO dispatcher; ProfilesViewModelTest drops
  its static Dispatchers mock (JVM-wide bleed class)
- Tests: WsProfileParams/Interceptor tests use the real prefs-backed state
  instead of mockkObject(AuthManager) (re-mock breaks in suite order after
  real AuthManager init); AuthManagerTest + Issue647ProfileUrlTest cancel
  the init() DataStore scope in tearDown (UncaughtExceptionsBeforeTest
  phantoms); regression test pins the clamp on the old path vs the new state

* fix(profiles): resolve getter/property JVM collision; de-poison slash test

- AuthManager.activeProfileId (StateFlow) and a getActiveProfileId()
  function generated the same JVM getter name — calls silently resolved to
  the property getter at runtime (ReadonlyStateFlow -> String
  ClassCastException, CI unit red 2026-08-06). Function removed; callers
  read activeProfileId.value.
- ChatViewModel: inject ioDispatcher (38 sites) so SlashCommandDispatchRpcTest
  can drop its mockkStatic(Dispatchers) bleed without racing real IO.
- SlashCommandDispatchRpcTest: drop the static Dispatchers mock (JVM-wide
  bleed; CI cross-wired COMMAND_DISPATCH captures in suite order), construct
  the VM with the test dispatcher.
