Implement four async DB-helper functions for memory_facts table:
- insert_memory_fact(user_id, content) -> int
- search_memory_facts(query) -> list
- delete_memory_fact(fact_id) -> None
- get_all_memory_facts() -> list
Add test_memory.py with 4 passing tests for these helpers.
All tests pass with mocked db_query.
