test(messaging): messaging and calendar sync integration suites (#22567)

13 integration suites driving the real sync pipeline end to end — OAuth
connect via the actual `/auth/google-apis/get-access-token` /
`microsoft-apis` callbacks (transient token + mocked provider token
exchange), real queue workers, provider APIs mocked at the HTTP layer
with msw.

**Messaging (8):** Gmail list fetch + import, Gmail folder discovery,
Microsoft folder discovery, history-based incremental sync, stale-sync
recovery, sync failure lifecycle (429 throttle → exhaustion → relaunch;
declined refresh token → insufficient permissions), token refresh,
connected-account cleanup cascade.

**Calendar (5):** Google events import (full + sync-token incremental),
Microsoft events import (delta fetch + import), stale-sync recovery,
failure lifecycle, cleanup cascade.
