Mini App join funnel: startapp sponsor attribution + wallet-app handoff

- /app decodes startapp=<sponsorId>[_<angle>] -> unlinked visitors land on the
  sponsor squeeze page /join/<ref>?src=miniapp (linked members still go to
  their dashboard); no-invite prospects get a gold Join button -> /join-now
- tg-app.js: sync __rmcInTg flag; external links route out of the webview via
  openLink/openTelegramLink (wallet deep links reach the wallet app reliably)
- join-now.js in the webview leads with the MetaMask/Trust deep links (no
  injected wallet can exist there); ref + src survive into the wallet browser
- tgbot: links command + weekly digest include the t.me/<bot>/<short>?startapp
  Telegram-native invite once config.miniAppShortName is set (new PATCH key)
- Synced chat.js canned answer + AI prompt (prospects can join from the app)
