Backend Developer 1 fb293a787d [8f7f167a] Redis mutex pre-lock write audit: add cross-session regression test for XPostService.approve
Audited x_post_service.py, video_post_service.py, release_proposal.py, and
heartbeat_mutex.py for the pre-lock DB-write anti-pattern (a session write
that happens before the SET NX / HeartbeatMutex acquire returns a token,
letting a losing racer's stale write clobber a winner's committed state).

XPostService.approve, VideoPostService.approve, and
ReleaseProposalService.approve/reject already implement the correct
validate-pure-pre-lock, apply-under-lock pattern (the XPostService fix
already shipped per CHANGELOG.md: "X edited_body write deferred into the
single-flight lock (M5)"). HeartbeatMutex holds no AsyncSession at all, so
the anti-pattern is structurally inapplicable there.

Adds a genuine cross-session concurrency regression test to
test_x_post_service.py (a real second DB connection, not an in-process
mock) mirroring VideoPostService's existing cross-session test, proving a
concurrently-committed post survives and the CEO's edited body never lands
on the just-posted row.
