Each saved file now records three additional fields:
matched_identifier — the literal animal_id_string or animal_name
substring that matched in the filename
animal_id_string_snap — snapshot of animal.animal_id_string at
registration time
animal_name_snap — snapshot of animal.animal_name at
registration time
This lets future consumers (scripts, exports, re-matching) identify
the subject from the file record alone, even if animal data changes.
The matched identifier is also shown in the drop preview UI (↳ 2852).
Tests: 25 total (+2 for new payload fields).

Adds a FileDropZone at the bottom of the day view where users can
drop all session files at once. Filenames are regex-matched to
subjects using their animal_id_string (word-boundary aware, so
"2852" won't match "28520"). Only metadata is recorded — files
are never uploaded.
Backend: new session_files table (id, daily_status_id, filename,
file_size BIGINT, file_type, last_modified, notes). Routes:
POST /api/daily-statuses/:id/files (batch create)
GET /api/daily-statuses/:id/files
DELETE /api/session-files/:id
Frontend: FileDropZone shows per-subject match groups, unmatched
files, and a warning for subjects with no match. After saving,
registered files are displayed with delete capability.
test-files/: generate_test_files.sh creates 4 dummy files per
subject (2×bin, 2×csv) with correct naming for drag-and-drop
testing. Pre-generated for 2026-04-23 with IDs 2852/3076/3077/3078.
Tests: 19 tests covering drag state, regex matching, save payload,
partial-overlap prevention, multi-subject batching, and delete.
