BREAKING: Replace hour/interval inputs with flexible time lists in Immich Album Watcher

Replace interval-based scheduling with explicit time lists for more flexibility:
- Periodic Summary: Replace interval_hours + start_hour with notification_times
- Scheduled Assets: Replace interval_hours + start_hour with notification_times
- Memory Mode: Replace start_hour with notification_times

Changes:
- Remove `periodic_interval_hours` and `periodic_start_hour` inputs
- Remove `scheduled_assets_interval_hours` and `scheduled_assets_start_hour` inputs
- Replace `memory_mode_start_hour` with `memory_mode_notification_times`
- Add three new time text inputs accepting comma-separated HH:MM format
- Replace hourly time_pattern trigger with three template triggers
- Update trigger logic to match current time against configured times
- Update documentation to reflect new time-based scheduling

Users can now specify any times (e.g., "09:00, 14:30, 21:00") instead of
calculating intervals. Times must use 24-hour format with leading zeros.
