Wallet help: SafePal + any-wallet in-app-browser path (not just MetaMask/Trust)

Mobile users on SafePal/Coinbase/Rabby had no route in — the deep-link help
only offered MetaMask + Trust. Added a wallet-agnostic instruction (open your
wallet app -> Browser/DApp tab -> type the join URL) that works via the
injected provider our EIP-6963 picker already resolves; join-now fills the
sponsor path into the hint. Dashboard no-wallet message made wallet-agnostic
and names SafePal. No guessed SafePal deep-link scheme (unverified).
