fix: worker startup crash and missing observation columns

Two bugs fixed:

1. SessionCompletionHandler called dbManager.getSessionStore() during
   WorkerService construction, before DB initialization. Changed to
   accept DatabaseManager and defer the call to runtime.

2. migration009 (generated_by_model, relevance_count columns) only ran
   via the deprecated MigrationRunner path, never through SessionStore's
   migration chain. Added addObservationModelColumns() to SessionStore
   constructor. Checks column existence directly since schema_versions
   may have been marked applied without the ALTER TABLE succeeding.

Also removed duplicate transcriptWatcher declaration and shutdown block
(merge artifact).
