feat: replace the Parity Signer QR flow with "track an address"

Keeps watch-only accounts, drops the protocol that cannot work.

ImportQr scanned a Parity Signer QR — SUBSTRATE_ID 0x53, CRYPTO_SR25519 0x01, a
crypto-type byte with no ML-DSA value — so no Quantus device could ever answer
it, and one branch hardcoded createAccountSuri(..., 'sr25519', ...). But it was
also the *only* caller of createAccountExternal, so deleting it would have taken
watch-only accounts with it. Those are wanted independently of how the address
arrives, and are what the account list is used for.

TrackAddress takes a pasted SS58 string instead, which for Quantus is the common
case anyway: the address is on screen in another wallet, not on a signing device.
It round-trips through decodeAddress/encodeAddress, which rejects a mistyped
address by its checksum rather than storing one that can never receive anything,
and normalises the prefix so an address pasted from a tool using a different one
displays the way the rest of the extension displays it.

The signing path had to change with it, and this is the part that would have been
a bug. `isExternal && !isHardware` previously rendered the QR signer — and a
tracked address satisfies exactly that condition, so leaving it would have shown
a Parity QR that nothing can scan, for an account that can never sign. External
accounts now show the decoded call and say plainly that the extension holds no
key for them.

That makes Signing/Qr.tsx unreachable, along with the CMD_MORTAL and
CMD_SIGN_MESSAGE Parity command bytes and the _onSignature callback, whose whole
job was accepting a signature produced outside the extension. All removed.

approveSignSignature in the background is deliberately left. Unlike Ledger, which
is gone for good, external signing returns when quantus/extension#10 ports the
flow to multipart UR — the message it carries is the right shape for that, and
deleting it would only mean writing it again.

Two specs rewritten rather than deleted: the one asserting a QR scanner appears
for external accounts now asserts the extrinsic and the cannot-sign warning
appear instead.

Typecheck, lint and 65 tests clean; build:chrome completes.
