Mirror the #5128 fast-path suffix repair when profile context is present
but requested_provider is omitted, which async delegation completion can
trigger via process_wakeup.

When session model_provider differs from profile model.provider, do not
expose profile_default_model for suffix repair. Fast path also requires
profile_provider to match requested_provider when profile_provider is set.
Addresses cross-provider mis-resolution (custom:other-proxy + bare suffix).

Refs #5127.
When _resolve_compatible_session_model_state takes the #1855 fast path with
a bare runtime model suffix and a slash-qualified profile default, repair to
the full qualified ID for custom/custom:* providers.
Also load profile model.default when the session already has model_provider
so wakeup turns can apply that repair.
