agessaman	7a851eee63	Implement database migration enhancements and connection configuration ... - Added `_apply_sqlite_pragmas` method in `DBManager` to configure SQLite connection settings such as foreign keys, busy timeout, and journal mode. - Updated `connection` methods in `DBManager` and `BotDataViewer` to utilize the new pragma settings. - Introduced validation functions in `db_migrations.py` to ensure proper identifier formats and table existence checks. - Created new migration functions for managing `packet_stream` and repeater-related tables, ensuring they are created and indexed correctly. - Removed redundant table initialization code from `RepeaterManager` and `BotDataViewer`, relying on migrations for table setup. - Enhanced tests to verify the creation of repeater tables and indexes during migrations.	2026-03-18 21:41:50 -07:00
