docs: fix typos and correctness issues in App Router docs - #97823

Correctness pass — following
#97823

## Summary

A systematic review pass over the App Router documentation
(`docs/01-app`, 281 MDX files) fixing clear-cut typos, grammar issues,
and technical inaccuracies — code samples, file names, and API
signatures that had drifted from the implementation in
`packages/next/src`.

The review ran four passes: an automated spell check with a triaged
allowlist, targeted grammar-pattern searches, structural checks
(frontmatter, code fences, link targets), and a technical-accuracy pass
over all getting-started pages plus high-traffic API reference pages,
with every suspected inaccuracy verified against the source before
editing. Only unambiguous issues were fixed; anything debatable was
deliberately left alone (e.g. the `/aboot` route in the typedRoutes docs
is an *intentional* invalid-route example, and the CLI docs table
intentionally mirrors the actual `--help` output).

Notable fixes:

- JSX examples now `await params`, matching the Promise-based API and
their TypeScript counterparts
- `generateStaticParams()` is now exported in samples so the convention
actually takes effect
- `<Link prefetch>` props table includes `"auto"`, matching the `boolean
| "auto" | null` type in `link.tsx`
- `Navigator.geolocation` casing, the canonical react.dev `"use client"`
link, and a missing `Link` import in the typedRoutes docs
- Mismatched or wrong `filename=` labels in TS/JS switcher pairs
(`form.mdx`, `mutating-data.mdx`, `css.mdx`) and a wrong
`generateStaticParams` anchor target
- ESLint monorepo example registers the plugin as `@next/next` so the
documented rule prefixes resolve
- Spelling/grammar: `emphaize`, `invokations`, `behaviour` → American
spelling, "setup" → "set up" as a verb (5×), "a RSC" → "an RSC",
`NextJS` → `Next.js`, a stray comma, and "a `opengraph-image.tsx`"
article plus its folder path

## Verification

- `cspell` over all 281 files in `docs/01-app`: 0 issues outside a
reviewed allowlist of product names, API identifiers, and intentional
example strings
- `prettier --check` (3.6.2, repo config): passes on all 19 changed
files
- Grammar-pattern and structure greps: clean
- Technical claims cross-checked against `packages/next/src` and
`packages/eslint-plugin-next`
- Docs-only change; no runtime code touched
