fix(events): Resource events now run on incremental syncs, fix output and progress bar

Three bugs fixed:

1. Early return in orchestrator when no discussions needed sync also
   skipped resource event enqueue+drain. On incremental syncs (the most
   common case), resource events were never fetched. Restructured to use
   if/else instead of early return so Step 4 always executes.

2. Ingest command JSON and human-readable output silently dropped
   resource_events_fetched/failed counts. Added to IngestJsonData and
   print_ingest_summary.

3. Progress bar reuse after finish_and_clear caused indicatif to silently
   ignore subsequent set_position/set_length calls. Added reset() call
   before reconfiguring the bar for resource events.

Also removed stale comment referencing "unsafe" that didn't reflect
the actual unchecked_transaction approach.
