Purge orphaned heartbeat run UUID from all tables before launch

The orphaned run 1fc2bf0e... triggers Paperclip's startup recovery
which overflows the stack via firstBlockedChainFinding. Even when
caught, downstream periodic checks crash Paperclip. Solution:
delete the UUID from every UUID column across every public table
before launch, so recovery has nothing to do.

Foreign-key constraint failures are swallowed per-row.
