Sidecar/queue runner no longer needs job-specific context. API server
resolves account details, IMAP auth, and user email at enqueue time —
all persisted in the job file. Handler reads directly from job meta.
Removed "Load account" step. Sync step auto-reconnects up to 10 times
when Gmail drops the connection, resuming from saved UIDs.
