fix(database): use BundledSQLiteDriver for consistent test behavior

- Use BundledSQLiteDriver in DatabaseBuilder for deterministic SQLite
  behavior across test environments
- Simplify DiscoveryMigrationTest to use context-free inMemoryDatabaseBuilder
  with BundledSQLiteDriver (removes ApplicationProvider dependency)
- Update migration doc comment to reflect version 39→40 path

Found during release/2.8.0 integration testing.
