frontend: COSS checkbox/table + fewer toolbar/sheet buttons

- Invoice dialog: the Back-date / Due-date toggles now use the COSS Checkbox
  instead of raw, misshapen native checkboxes.
- Patients page: rebuilt the list as a COSS Table in a CardFrame, and moved
  "Import from a patient app" into a ⋯ overflow menu so the toolbar keeps one
  primary "Add patient" CTA.
- Patient detail sheet: collapsed the five header buttons + delete into a
  primary Edit action plus a ⋯ More menu (Download summary, Record visit,
  Transfer, Push to wallet, and a destructive Delete).
- Added the COSS table + checkbox primitives; new i18n keys across all locales.
