Both workloads have been promoted into cardano_node_master (tx-generator
in ecf7910, asteria-game in subsequent commits), and the dedicated
testnets only duplicated the master configuration without exercising
anything new. Removing them collapses the publish-images CI to a single
smoke test (master), removes scripts/push-asteria_game_images.sh, and
trims mkdocs/docs accordingly.

testnets/cardano_node_adversary is intentionally left untouched —
its workload has not yet been promoted to master.

Component services (tx-generator, asteria-game, etc.) are untouched.

fix(gateway): reject `/sdk/ws` upgrade when Hydra is not configured

added:
* github:input-output-hk/mithril/afdbf61f7260e7d2680f42d4007f304d4bfdfb49#mithril-client-cli
* github:input-output-hk/mithril/afdbf61f7260e7d2680f42d4007f304d4bfdfb49#mithril-signer
removed:
* github:input-output-hk/mithril/e0ad33fc9af51e9cd85e6a3db3a7ddea6fa49cab#mithril-client-cli
* github:input-output-hk/mithril/e0ad33fc9af51e9cd85e6a3db3a7ddea6fa49cab#mithril-signer

Extend `lib/dummy-ghc.nix` and the `tests.dummy-ghc-info` filter
list so the dummy's `--info` matches the real cross/native GHC
`--info` for the variants tested in hydra:

  * aarch64-multiplatform (linux-gnu cross, Stage 1, no `_dyn`
    RTS ways) — add a cross-linux-gnu branch alongside
    android/static, keyed off cpu mismatch so libc-only crosses
    (musl64) fall through to the native branch.
  * `cross compiling` field now compares cpu + kernel rather
    than the full platform triple, matching what GHC itself
    reports (libc differences alone are not cross).
  * musl32 (i686-linux-musl) and ucrt64 (x86_64-w64-mingw32):
    `platformString` normalises `i686 -> i386` and the
    Windows vendor/kernel pair to `unknown/mingw32`, matching
    real GHC's `Target platform` / `target platform string`.
  * ghc967 native and musl64: branch the RTS-ways string on
    GHC version (9.6 uses a smaller, differently-ordered set
    than 9.8+) and on libc (the 9.6 musl bootstrap reports a
    12-way set while stock nixpkgs 9.6.7 reports 10).

Test-side: add a small set of per-version cosmetic fields to
`ignoredFields` (`GCC extra via C opts`, `LLVM clang command`,
`ld command`/flags, `dllwrap`, `touch command`,
`target RTS linker only supports shared libraries`) that don't
drive cabal-install elaboration.

Verified `tests.dummy-ghc-info` passes on linux-0 (with
`--builders ''`) for: ghc9141 native + aarch64-multiplatform,
ghc9124 musl32 + ucrt64, ghc967 native + musl64.
