- auto_cycle.py: _scheduler_loop now distinguishes weekday (interval_hours)
from weekend (weekend_cycle_times UTC slots or sleep until Monday);
_parse_weekend_times() and _next_weekend_slot() helpers;
get_status() exposes weekend_cycle_enabled + weekend_cycle_times
- cycle.py: CycleConfigRequest adds weekend_cycle_enabled + weekend_cycle_times;
update_cycle_config validates HH:MM format and persists to config DB
- Config.tsx: weekend scheduling section with enable toggle + time picker
(06:00/08:00/12:00/18:00/22:00/00:00 UTC presets, multi-select);
weekendEnabled + weekendTimes state synced from cycle status
Default: enabled with 08:00 + 22:00 UTC (covers news scan + Globex open Sunday)
