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)

      a:()=>`A pyramid or Ponzi scheme funnels everyone's money to a central company and pays earlier joiners out of later joiners' deposits — and you can't verify any of it. This is the opposite: <strong>no company holds the money</strong>. A public smart contract on Polygon sends each payment person-to-person in the same transaction it arrives, and you can read the code and every payout yourself on-chain — nothing pooled, nothing hidden, rules that can't be changed. It <em>is</em> a team build, so it takes real effort and carries real crypto risk — not a passive investment. But you don't have to trust anyone; verify it at <a href="/contract">rmcircle.team/contract</a>. No income is guaranteed.`},

      a:()=>`Three good paths, easiest first: (1) <strong>E-gift cards</strong> — send POL to CWallet (cwallet.com), swap to a US-dollar token there (their internal swaps are virtually free), and buy gift cards for brands you already use — groceries, gas, Amazon. eGifter (egifter.com) also takes crypto directly. (2) <strong>Straight cash-out</strong> via a regulated exchange in your country (Coinbase, Kraken…): send, sell, withdraw to your bank. (3) <strong>Keep it working</strong> — many members leave catches in the wallet to fund their next level. Full guide: <a href="/training#spending">Spending what you earn</a>.
