fix: avoid projection rebuild under dedupe lock (ticket-216)

[tom-sapletta-com]

Delivery

Ticket-216 / PLF-18410: use existing nonrepairing ticket lookup inside deduplication mutation lock. Stale/missing SQLite projection falls back to authoritative sources instead of rebuilding every archive while holding the writer lock. Normal index maintenance is unchanged.

Validation

Eight deterministic regressions failed before the change and pass afterward: missing/stale projection, current/archived ticket, with/without occurrence notes. 45 focused tests passed; full suite 1273 passed, 6 skipped. Ruff and governance clean. Protected OneDev and independent Validator required. No deployment claimed for this change.
