Refresh views during one-shot schedule cleanup

[joshua-spacetime]

Description of Changes

Fixes a bug where clients subscribed through views could miss delete updates when a one-shot scheduled reducer or procedure completed and the scheduler automatically deleted the corresponding schedule row. This patch ensures that scheduled-row cleanup refreshes any stale views before commit/broadcast.

Note, this only affected one-shot schedules. Interval schedules do not delete their schedule row after each run, so they were not going through this path.

Testing

Added regression coverage for:

• one-shot scheduled reducer: table + view subscription sees insert then delete
• one-shot scheduled procedure: table + view subscription sees insert then delete
• failing scheduled reducer: cleanup still refreshes the dependent view delete
• observe transitive scheduled table updates through join

The one-shot tests now assert on the scheduled table and dependent view in the same subscription updates, which proves the delete comes from the automatic cleanup transaction itself rather than a later manual write.
