Fix Toggle All button state, stop icons, and Disable tooltip

- Fix Toggle All button always showing Start: /picture-targets list
  endpoint does not include processing state; now fetches
  /picture-targets/{id}/state per-target in parallel in both
  loadProfiles() and toggleProfileTargets()
- Replace pause icons (⏸) with stop icons (⏹) in dashboard
- Change profile automation toggle tooltip from 'Disabled' (status)
  to 'Disable' (action); add profiles.action.disable i18n key
