Jon Chery 0358efe95b fix(P07): concurrency safety — SQLite, flock, cache, atomic writes (REQ-156) ...

- SQLite busy_timeout(5000) + SetMaxOpenConns(1) on all 4 DSNs
- secrets file flock (concurrent set on same ns no longer loses data)
- upgrade lock file (refuse concurrent orca upgrade)
- backup lock file (refuse concurrent backup)
- cache invalidation by writes (read-after-write consistency)
- Executor.Run mutex scope fix (hold only for DB inserts)
- ns create/inherit/set-constraint atomic writeNSMdAtomic
- writeCurrentLead + rotateSSHKeys atomic
- consolidate 3 writeAtomic impls onto security.WriteAtomic
- WebAuthn session stores guarded with sync.Mutex

Tests: concurrent secrets set, upgrade lock rejection, cache
read-after-write, WebAuthn session thread-safety (pass under -race).
