increase sql retries

[dphuang2]

• fixes flaky DB locked errors in CI

---

Note

Improves SQLite robustness under lock contention and during initialization.

• Adds connect_with_retry to ensure pragmas are applied even if initial connect() hits lock errors; closes partial connections and retries with backoff
• Increases retry limits to SQLITE_RETRY_MAX_TRIES=10 and SQLITE_RETRY_MAX_TIME=60s
• Replaces direct db.connect() with connect_with_retry in SqliteEventBusDatabase and SqliteEvaluationRowStore
• Wraps create_tables(...) calls with execute_with_sqlite_retry to handle transient lock errors during schema creation
