fix: remove the fork-with options, and name the workflow step for what it does

**Fork with Chopsticks / Forklift is gone.** Neither can fork a chain in this
list. Chopsticks is built on `@polkadot/types`, which cannot decode a Quantus
block at all — it caps fixed arrays at 2048 bytes where ML-DSA signatures are
5261 and 7219, reads the extrinsic preamble byte as a version, and knows nothing
of this chain's header layout. Forklift resolves its own unpatched copy of
`@polkadot-api/substrate-bindings`, so it hits the very header bug this console
patches around.

So the two buttons offered things that could only fail, and fail without saying
why. Removed rather than disabled: a greyed-out control still asks the reader to
work out why. `forkMethod` stays in SelectedChain because the hash params and
chain.state still read it; nothing in the UI can now set it to anything but
"none", so the two light-client guards that reset it go with it.

**The workflow step called "the patch is applied"** — an assertion sitting in a
list of imperatives (install, build, ship the bundle), reading like a claim CI
was making rather than a thing it was doing. Now "verify the signers-common
patch".

Verified in a browser: the switcher shows Quantus, Heisenberg, Planck and
Localhost with both endpoints per chain and no FORK WITH row, and the explorer
still runs — Finalized 54,153, Best 54,253.
