fix: schedule status system — auto-key, config order, label lookup

- Auto-generate status key from label (admin doesn't need to set keys)
- Remove visible key field from status config editor
- Order statuses/levels in filters by config order (matches admin panel)
- Shared findStatusConfig() for robust label lookup (by key, label, or derived key)
- Custom status badges in DayCard, GroupCard, MobileSchedule
- Simplified filter logic with clsStatus helper
- Removed dead code: TIME_PRESETS, StatusFilter type
- SelectField: blur input after selection to prevent re-open
