Fix STEP numbering, logging, and replication in resurrection test

Multiple fixes to improve test clarity and fix document resurrection:

1. Fix STEP numbering consistency:
   - STEP 1-6: Setup and tombstone purge (unchanged)
   - STEP 7: NEW - Touch document to force push
   - STEP 8-14: Renumbered for consistency (was 7-13)
   - Comments now match log output

2. Add document modification before reset checkpoint:
   - Touch doc1 by adding _resurrection_test field
   - Forces CBL to detect change and push during reset
   - Fixes issue where doc wasn't pushed after reset

3. Improve logging and output capture:
   - Use reporter.log() for all test output
   - Remove println!() from create_doc helper
   - Add detailed logging for each verification
   - Log replication events explicitly after reset

4. Increase wait time after reset:
   - 10s → 30s to allow replication to complete
   - Log number of replication events captured
   - Warn if no events (indicates push didn't happen)

These fixes address:
- Logs were incomplete (println!() not captured)
- STEP numbers didn't match (comments vs logs)
- Document wasn't pushed after reset (no change detected)
- Hard to diagnose issues without replication event tracking
