feat: add litter box alert and kiosk dashboard automations

Add new automation files to the Home Assistant configuration:

- 02a_litter_box_alerts.yaml: Notifications for multiple litter boxes
  (Poop Box, Triple Threat, Cat Crapper 3000, The Deuce, and Luma
  Smart) covering waste bin full, low litter level, door error, and
  deodorant empty alerts, leveraging shared notification blueprints
- 06a_kiosk_dashboards.yaml: Automations for managing kiosk dashboards

These automations centralize pet-care and maintenance notifications
so alerts are triggered consistently across devices.
