chore(docs): update dependencies and adapt to zbsearch 4

fumadocs-core 16.14.5 switched its search engine from Orama to zbsearch 4,
so the panel docs follow it up to the same major.

zbsearch 4 still rejects locale codes as tokenizer languages ("en" throws,
only "english" is accepted), so the custom search dialog that forces an
English index stays necessary — verified by loading the built static index
for all four locales and searching it through fumadocs' own client.

Around that:
- use `staticClient`, as `oramaStaticClient` is now a deprecated alias
- drop @orama/orama, which nothing depends on or imports any more
- correct the two comments that still described Orama and pointed at its
  docs and tokenizer package, one of them suggesting a language zbsearch
  does not have
- restore the corepack integrity hash on `packageManager`, which CI reads
  through pnpm/action-setup
- prune minimumReleaseAgeExclude entries for versions no longer installed

The API reference MDX changes are serialization-only: fumadocs-openapi
11.2.4 emits plain scalars where it used folded ones. Parsed frontmatter
and page bodies are unchanged.
