- Sleep: store per-epoch stage timestamps in new sleep_stages JSON column;
DailySnapshot now renders a proper 4-lane hypnogram (Awake/REM/Light/Deep)
instead of the old proportional flat bar
- Body battery: replace grey background bars + white line with per-minute bars
coloured by inferred type (sleep=indigo, rest=teal, active=orange, stable=grey)
derived from sleep window + battery direction; Y-axis fixed 0-100
- Routes: convert sidebar list to tile grid sorted by most completions; tiles
colour-bordered by sport type (blue=running, orange=cycling); completion count
shown on each tile; detail panel displays below the grid when a tile is clicked
- Segments on activity detail: add column headers (This run / Best / Δ) and
show signed time delta vs best, green when faster, red when slower

The Garmin FIT SDK returns snake_case field names but the parser was
looking for camelCase. Sleep epoch durations were wrong (fixed 30s each
instead of computing from timestamp gaps). HRV is in message 370 not 275
(275 now carries sleep levels in modern firmware). Multiple fixes:
- msg 55: use 'steps', 'heart_rate', 'active_calories' (not numeric keys)
- msg 211: use 'resting_heart_rate' (not msg.get(0))
- msg 227: use 'stress_level_time'/'stress_level_value' for named fields
- msg 132: use snake_case 'stress_level_time'/'stress_level_value'
- msg 275: detect sleep_level field → handle as sleep epoch (modern),
fall back to HRV handling for older firmware
- msg 370: new handler for modern hrv_status_summary (last_night_average,
last_night_5_min_high, status)
- msg 346: new handler for sleep_assessment → overall_sleep_score
- msg 21: new handler for sleep session start/stop events to close the
last sleep epoch and record sleep_start/sleep_end timestamps
- Sleep duration: computed from epoch timestamp gaps instead of 30s/epoch
- Celery task SQL: add sleep_score, sleep_start, sleep_end to INSERT/UPDATE;
use GREATEST for total_calories so most-complete value wins across files
