frontend: UI fixes + settings/patients features

- Record history: replace fragile COSS Timeline separator math with a
  continuous-rail list so every audited change renders in full (RTL-safe).
- Prescriptions: new reusable COSS DatePicker (Popover + Calendar) replaces
  raw <input type="date"> for Start/End date.
- Update banner: rebuilt with COSS Alert variant="warning"; pinned physical
  bottom-right so it stays bottom-right under Arabic RTL.
- AI setup notice: thin attached warning banner with clearer copy; now shown
  above the input in active chats too, not just the empty state.
- Settings profile: wire the previously dead Specialty (Select) and
  Professional links (editable rows) into the persisted preferences.
- Patients: add a status filter and broaden search to conditions/allergies.
- Sidebar user menu: quick language switch submenu (RTL already wired).
- ai-elements: fix a subset of Base UI type drift (22 -> 12; remainder is
  cmdk->Autocomplete migration drift kept behind ignoreBuildErrors).
- i18n: new keys added across all five locales (en/de/fr/ar/so).
