v0.9.73 — Slack channel connector and stability release

Promotes latest main to production.

Highlights:

• Slack native channel connector consolidation and CLI parity fixes.
• DB migration backfills executor_connector_provider=channel on faked-baseline prod databases so Slack channel connector materialization works.
• Live-schema deploy gate now checks enum values, preventing this drift class from recurring.
• Includes latest main stability/dependency updates already green on main.
