* fix(core): use INSERT ON CONFLICT DO NOTHING for provider model sync
Replaces try/except around model.create_async() with pg_insert()
.on_conflict_do_nothing() to prevent UniqueViolationError from being
raised at the asyncpg driver level during concurrent model syncs.
The previous approach caught the exception in Python but ddtrace still
captured it at the driver level, causing Datadog error tracking noise.

Adds automatic retry with exponential backoff for PostgreSQL deadlock
errors (40P01) in all ORM write methods: create_async, update_async,
batch_create_async, hard_delete_async, and bulk_hard_delete_async.
For update_async, column values are snapshotted before the commit
attempt so they can be restored after rollback clears them.
Also adds DatabaseDeadlockError to _handle_dbapi_error as a fallback
when retries are exhausted.

The handle_db_timeout decorator only caught SQLAlchemy's TimeoutError
(for pool/connection timeouts) but not asyncpg's QueryCanceledError
which is thrown when PostgreSQL's statement_timeout kills a long-running
query.
This fix:
- Import asyncpg.exceptions.QueryCanceledError
- Update handle_db_timeout decorator to catch QueryCanceledError and wrap
it in DatabaseTimeoutError
- Update _handle_dbapi_error method to also handle wrapped QueryCanceledError
