Refactor session ID references from sdk_session_id to memory_session_id across multiple services and database queries

- Updated SQL queries in cleanup-duplicates.ts and context-generator.ts to use memory_session_id.
- Modified interfaces in context-generator.ts to reflect the new session ID naming.
- Implemented a repair migration in SessionStore.ts to rename columns in existing tables.
- Adjusted FormattingService.ts and SDKAgent.ts to utilize memory_session_id for session handling.
- Ensured SearchManager.ts retrieves summaries and observations using the updated memory_session_id.
