fix(libsql): standardize timestamp storage to RFC 3339 with UTC offset (#663)

Replace all `datetime('now')` defaults in libsql_migrations.rs with
`strftime('%Y-%m-%dT%H:%M:%fZ', 'now')` so new rows get proper RFC 3339
timestamps (e.g. `2024-01-15T10:30:00.123Z`) instead of naive datetimes
(e.g. `2024-01-15 10:30:00`).

Add tracing::warn! to parse_timestamp() naive fallback paths so legacy
timestamps are still accepted but produce a visible deprecation signal.

Backward compatible: no data migration needed; existing naive timestamps
continue to parse correctly via the multi-format fallback.
