Scheduler now accepts comma-separated HH:MM times in daily schedules.
Each time slot is independently evaluated - if any slot has passed and
last_sync is before it, the table is marked as due.
This lets tables sync multiple times per day to pick up data refreshes
that happen throughout the day (e.g., Keboola pipelines running 3x/day).
- New sync_schedule and profile_after_sync fields in TableConfig
(formats: "every 15m", "every 1h", "daily 05:00")
- New src/scheduler.py with schedule evaluation logic (is_table_due)
- New --scheduled mode in data_sync.py: only syncs tables that are due,
respects profile_after_sync flag, auto-restarts webapp after profiling
- Systemd timer+service for data-refresh (every 15 min)
- Systemd timer+service for catalog-refresh (every 15 min)
- deploy.sh enables new timers automatically
- Complete table config reference in data_description.md.example
- 58 new scheduler tests
