frontend+backend: patients/settings UI, AI Auto/Off modes, wallet doc push

- patients: move status filter to its own "Filter" row above the table
- patient sheet: name + ⋯ menu on one left row; Edit moved into the ⋯ menu
- settings: redesign sections with the COSS CardFrame surface (SettingsFrame)
- AI: add Automatic (auto-pick provider) and Off modes; default to Automatic
  so a fresh install shows the setup banner until a provider is configured
- AI: fix the setup banner never showing (defaulted Ollama URL counted as
  configured); add an "AI off" notice; add a fallback render for unknown chat
  data parts so cards never silently vanish
- backend: include patient attachment metadata in the wallet record-update
  bundle so pushed documents reach the wallet
- i18n: add mode/off/card keys across all five locales
