Database migration:
- ALTER TABLE accidents RENAME COLUMN employee_name TO submitter_email
- ALTER TABLE accidents RENAME COLUMN responsible_person TO injured_person
- ALTER TABLE accidents RENAME COLUMN employee_id TO injured_person_id
Reason: Accident.employee_name contained submitter EMAIL (not staff name),
causing confusion when joining with attendance_records.employee_name (real name).
New column names are self-documenting.
API backward-compat:
- All API responses still use "employee_name" / "responsible_person" field names
- Internal SQL mapping translates submitter_email/injured_person -> employee_name/responsible_person
- Frontend code unchanged
Verified:
- /api/accident/1 returns employee_name = submitter_email content
- /api/accident/records returns 2 records OK (was 500 before fix)
- /api/employees/list still returns 12 staff (accident excluded)
- Data preserved (1st record id=1 submitter_email = info@scmedical.hk)
