Closes CL-11970

Summary

• Only offer Use and show Active on model profiles in Settings → Profiles when every tier's provider is connected and available; fall back to automaticProfile or the unresolved banner when a previously saved profile's provider is disconnected.
• Filter the Start from list and tier provider options in the custom profile editor to connected providers (keeping any disconnected provider currently bound on an edited custom profile as a disabled option so it is visible while blocking Save until replaced).
• Invalidate keys.modelChoice when personal profile settings are saved so the home prompt picker updates immediately.
• Enforce connected provider availability in invalidModelChoice, resolveModelChoice, and frozenModelChoice on the hub so disconnected profiles cannot be activated or resolved as a project's model choice.
