Claude 5f16ebc060 feat(quartz): NIP-BC sign_psbt over NIP-55 external signer (Phase B) ...

Wires the NIP-55 Android external-signer contract for sign_psbt, so
NostrSignerExternal.signPsbt is real instead of a stub.

- CommandType.SIGN_PSBT ("sign_psbt") — also available in NIP-55 `perms`
  lists, since Permission wraps CommandType directly.
- SignPsbtResult result type.
- SignPsbtQuery (background ContentResolver) + SignPsbtRequest /
  SignPsbtResponse (foreground Intent), modeled on the derive_key
  string-in/string-out shape: the PSBT hex rides the `nostrsigner:` URI,
  the signed (not finalized) PSBT comes back in the `result` field.
- BackgroundRequestHandler.signPsbt / ForegroundRequestHandler.signPsbt.
- NostrSignerExternal.signPsbt now runs the background-then-foreground
  query. Signer apps that predate sign_psbt reply with no `result`, which
  surfaces as CouldNotPerformException — the send dialog shows it as a
  failure ("update your signer").

NIP-46 (NostrSignerRemote) still throws UnsupportedMethodException — the
bunker-side command isn't standardized yet.
