Replaces the wrong approach (stage + try to bounce into the app, which iOS blocks)
with the one Teams/WhatsApp actually use: the picker and the send happen INSIDE the
share extension, so there's no app-open at all. Tap Share → Biz Connect → pick a
chat → it uploads and sends, right there in the sheet.
How the extension can send without the app: it's a separate process that can't see
the web app's HttpOnly cookie, so:
- server: GET /api/share/token mints a bearer token for the logged-in user.
- web: on every launch the app fetches that token and hands it to the extension via
the App Group (ShareInbox.setAuth writes token+base to the shared UserDefaults).
- extension: reads the token and calls the SAME API the native client uses —
GET /api/messages/conversations to list chats, POST /api/messages/upload for each
file, POST /api/messages to send. Native UITableView picker with search.
Robustness: it still stages the files + writes a manifest first, so if there's no
token yet (user never signed in) or the send fails, the file isn't lost — the app
collects it on next open, exactly as before. On success the manifest is cleared so
the app doesn't re-offer it.
Server + web are live now; the token endpoint is harmless until a build ships the
extension. NEEDS A NEW iOS BUILD for the picker itself.
