fix: admin records filter by user_id instead of keyword search

- RecordView passes user_id as separate filter param, not as keyword
- Admin records endpoint forwards user_id to DAO
- treatmentDao.listAdmin supports exact user_id match filter
- Added visible filter tag with clear button in RecordView
