Waleed 3ff91f0439 improvement(docs): clean up leftovers from the code-block alignment PR (#6825)
* improvement(docs): clear leftovers from the reverted revisions

A cleanup pass over the final state. Every finding was residue from an approach
this PR tried and abandoned, or a claim that stopped being true when it did.

- Delete the copy-button svg sizing rule: a later rule sets `display: none` on
  that same element ungated, so sizing it was never observable. Superseded by
  the mask approach.
- Drop the paragraph in page.tsx arguing about a custom Shiki factory. The
  factory was deleted; nothing configures one now.
- Correct shiki-curl-json.ts, which still claimed the grammar "reaches the
  client path too". It does not — that was the justification for choosing a
  grammar over a transformer, so leaving it stated the opposite of the truth.
  Now records where it applies, where it does not, and why not to retry.
- Correct the global.css section header, which claimed the component owns the
  shell while the next rule defines it here.
- Qualify the `--copy-glyph` declarations with `:has(> svg[class*="lucide"])`,
  which the group's own comment asserts of every rule in it.
- Correct `getCode`'s TSDoc: the gutter is a `::before`, and pseudo-element
  content never reaches `textContent`, so line numbers were never what the
  clone guards. It guards transformer-emitted `.nd-copy-ignore` nodes.
- Compose `chipGeometryClass` and emcn's `ChipChevronDown` in the API example
  selector instead of restating their literals.
- Merge the duplicated `div[role="region"]` rule. The tablist pair stays split:
  biome's `noDuplicateProperties` reads a nested `@variant` setting the same
  property as a duplicate and fails the build — recorded so it is not remerged.
- Note that fumadocs ships its own gutter for `lines`-meta fences, which cannot
  be suppressed from here and would paint a second column.

* fix(docs): drop a highlighter registration that can never fire

fumadocs-openapi calls `renderCodeBlock` with a hard-coded `"json"` from both of
its call sites (`request-tabs.js:76`, `response-tabs.js:48`), so the docs
`CodeBlock` it routes through never receives a shell language. The
`getHighlighter('js', { langs: [curlJsonBodyGrammar] })` registering the
shell-scoped JSON-body injection therefore did nothing but await on every API
sample render, and the docblock claiming the grammar covers those samples was
wrong.

- Delete the call and its imports.
- State the grammar's real coverage: prose fences only, via `langs`. Both API
  reference paths are unreachable — samples are JSON, and the cURL usage tabs
  highlight client-side off fumadocs' own factory.
- Correct `code-block.tsx`'s TSDoc, which still said API samples come from
  fumadocs' own renderer. They come through this component; `UsageTab` is the
  renderer that bypasses it.
- Re-home a comment orphaned when two CSS rules merged — it had drifted onto
  the rule below and read as documenting it.
- Drop a `.nd-copy-ignore` claim about transformers emitting those nodes;
  nothing here does, and upstream parity is the reason the clone exists.
