fix(sync,web): surface exhausted jobs and skip draft compass hop

[tyler-dane]

Summary

Surfaces Sync jobs that exhausted the self-heal requeue budget so operators can find and clear/requeue wedged work, and removes the unnecessary CompassEvent hop on the Week draft render path.

• Diagnostics include failedJobCount / exhaustedJobCount
• Self-heal sweep logs a bounded sample of exhausted job ids/keys
• New CLI: bun run cli manage-failed-jobs list|clear|requeue
• Week Draft / GridDraft project GridEventDraft → GridEvent directly

Simplicity

Shared the exhausted-job Mongo filter between count/list helpers. CLI list reports true count + truncation rather than treating the sample length as the total. No new React state/effects.

Automated validation

• Focused sync DB tests for job repository + failed-job requeue (pass)
• Diagnostic contracts + diagnostic routes DB tests (pass)
• Web: grid-event-draft adapter + GridDraft tests (pass)
• bun run type-check and bun run lint (pass)

Independent review

Fresh diff review confirmed three CLI issues; all fixed before merge:

1. list under-reported when sample capped — now uses countExhaustedFailed + truncated
2. clear could delete non-failed jobs — now requires state === "failed"
3. clear --apply ignored remove() failure — now throws on false

No confirmed defects on the draft → GridEvent projection path.
