feat: offer only signers that can sign for Quantus

The Quantus runtime accepts only ML-DSA signatures. qapi offered every signer
polkahub knows, and none of those could sign here:

- Polkadot Vault, Ledger and WalletConnect produce sr25519, ed25519 or ecdsa
  signatures (and WalletConnect was configured only for Polkadot, Kusama and
  Paseo);
- the external multisig signer hands signing to multisig.usepapi.app;
- the browser-extension list offered polkadot{.js}, Nova, Talisman,
  SubWallet, PolkaGate and Fearless.

These providers, their management buttons, and the Vault and multisig modals
are removed. What remains: browser extensions, read-only (watch) addresses,
and proxies, which sign through whichever signer they wrap.

@polkahub/pjs-wallet is patched (pinned to 0.9.1, like the substrate-bindings
patches) so the extension list is blackbeard alone, with its sigil as the
logo. Its provider only ever sees, offers or connects blackbeard: anything
else injected into window.injectedWeb3 is ignored, not merely unlabelled.

Verified against a local build in Firefox with blackbeard installed. The
Account Providers panel shows blackbeard (with the sigil), Address and Proxy,
and nothing else, including after fake polkadot-js and talisman entries were
injected into the page and the provider's 2 s re-scan had run.
