refactor(ui): unify LanguageSelector, ConfirmDialog, and AppSlider across apps

- contacts, zitare: migrate LanguageSelector to shared PillDropdown pattern
- context, times: replace local ConfirmDialog with ConfirmationModal from @manacore/shared-ui
  - delete local ConfirmDialog.svelte in both apps
  - map open→visible, onCancel→onClose, remove destructive prop (default in shared-ui)
- calendar, chat, contacts, presi, todo: switch AppSlider from static MANA_APPS
  to getActiveManaApps() to filter inactive apps consistently
