Missing participant record: TO049 (speaks in TOA3007)

[ellepannitto]

Cross-checking transcripts against metadata (see kiparla-tools check_participants.py) found a gap:

• Speaker TO049 appears in tsv/TOA3007.vert.tsv and is correctly listed in that conversation's participants column in metadata/conversations.tsv.
• TO049 has no corresponding row in metadata/participants.tsv.

Needs a participant record added for TO049 (occupation, gender, birth-region, age-range, study-level, etc.) to metadata/participants.tsv.

Partial fix applied: added a TO049 row to metadata/participants.tsv (code + conversations=TOA3007, confirmed against the source EAF tier), so the back-reference is now consistent.

All other demographic fields (occupation, gender, birth-region, age-range, study-level) are still empty (_) — need to be filled in with real data. Leaving this issue open for that.
