[BUG] Airtable webhook sources intermittently emit the raw Airtable payload

[mariczne]

Describe the bug
Airtable webhook sources intermittently emit the raw Airtable payload (instead of the normalized shape with originalPayload). I assume this is due to a throw during event processing for createdRecordsById due to errors fetching the new record immediately after the webhook arrives.

Root causes:

• Fallback path (emitDefaultEvent) emitted the raw payload instead of a normalized shape.
• emitEvent destructured changedTablesById without guarding against empty/unknown shapes.
• For create events, a GET to /v0/{base}/{table}/{recordId} can briefly return an error (e.g., not yet consistent), which caused the emitter to throw.

To Reproduce
Steps to reproduce the behavior:

1. Set up an Airtable webhook source (New/Modified/Deleted or New/Modified Records).
2. Create records via Airtable
3. Observe occasional events where:
   • The step output is the raw payload (no originalPayload), or
   • The source errors due to an exception during event emission.

Expected behavior

• All events should have a consistent, normalized shape including originalPayload.
• Emitters should not crash on unexpected payload shapes.
• Record fetch should be best-effort: retry briefly and, if it still fails, emit the event with empty record.fields instead of throwing.

Screenshots
N/A (behavior is visible in step logs and event payloads).

Additional context
I'll create a PR addressing this bug.

Hey @jcortes, there is a PR that is supposed to address this: #18221
