Pull request overview

Adds Sentry-based error reporting for persisted table replication errors by decorating the replicator state store, and refactors Sentry event construction to better handle EtlError.

Changes:

• Introduces ErrorReportingStateStore to report TableReplicationPhase::Errored updates to Sentry (and optionally to the existing Supabase error-notification endpoint) after state persistence.
• Refactors Sentry event creation by extracting event_from_etl_error and adding capture_table_error with a table_id tag.
• Adjusts where the etl_worker_errors_total counter is incremented in the table sync worker.
