Update documentation anchors for VitePress compatibility (#19221)

* Update documentation anchors for VitePress compatibility

Update @link annotations in Hash.php and Text.php to use the new
VitePress-compatible anchor format. The documentation book now
uses VitePress which generates anchors differently from the old
RST/Sphinx setup.

Related: cakephp/docs#8157, cakephp/docs#8158

* Update additional documentation anchors for VitePress compatibility

- FormHelper: use section heading anchor instead of Cake\ class path
- Controller: use section heading anchor for redirect
- HtmlHelper: fix programmatically typo to match docs heading
- ServerCommand: fix page URL (console-and-shells → console-commands/commands)
- ConsoleIo: fix page URL (console-and-shells → console-commands/input-output)
- Debugger: use existing section heading anchor
- TranslateBehavior: fix I18n locale anchor to match setLocale heading

Ref cakephp/docs#8160

* Fix SecurityHeadersMiddleware link to dedicated docs page

The middleware has its own page at security/security-headers
instead of an anchor on the middleware page.

* Fix pluginSplit anchor casing for VitePress

VitePress lowercases all heading anchors, so pluginSplit() generates
#pluginsplit not #pluginSplit.

* Fix broken @link annotations and add missing doc links

Fix 3 broken links:
- FormHelper::year() anchor: #creating-year-inputs → #creating-year-controls
- Configure::load() anchor: #reading-and-writing-configuration-files → #reading-writing-configuration-files
- CookieCryptTrait: remove dead link (controllers/components/cookie.html returns 404)

Add missing @link for documented methods:
- Text: uuid, tokenize, insert, cleanInsert, wrap, wrapBlock, tail, transliterate, slug
- HtmlHelper: linkFromPath (more specific anchor), media
- ConsoleIo: out, err
- Controller: loadComponent
