Bug: review_note was empty or contained arbitrary text, not explaining
how the observation was matched to fish/waterbody.
Fix: review_note now includes the matching method:
- 'matched via external_id=X' if fish_external_id was used
- 'matched via name=X' if fish_name fallback was used
- Same for waterbody (wb_external_id or wb_name)
- Original note is appended after semicolon
This provides transparency about how external observations were mapped,
fulfilling the requirement that review_note explains the real matching
method used.
Verification:
- 124/124 Python tests pass
- Existing tests still pass (review_note is optional parameter)
- New review_note format is machine-readable and human-friendly
