Scott Idem 3db5f7c749 fix(P3): guard startup db connection with try/except in lib_sql_core ...

Wraps the deprecated global `db = engine.connect()` in a try/except so
a Docker startup race (MariaDB not yet ready) no longer crashes the
Gunicorn worker before it can serve any requests.

Sets db=None on failure; reconnect_db() on the lifespan bootstrap path
re-establishes it once credentials are confirmed.

TODO (P3 full): migrate lib_schema_v3.py:39 and lib_api_crud_v3.py:166
off the global db to engine.connect() context managers, then remove it.
