Add CookiesNotice plugin with embedded HTML and CSS resources

[Copilot]

Adds a CookiesNotice Statiq plugin that injects a dismissible cookie consent banner into rendered HTML pages, backed by madmurphy/cookies.js.

New plugin (src/Statiq.Plugins/CookiesNotice/)

• CookiesNoticeModule — ParallelModule that post-processes .html destinations, loading a template and styles from embedded resources and injecting the rendered notice before </body>. Config values are HTML-encoded; cookie name is sanitized to safe characters.
• CookiesNoticeConfigurator — Wires the module into the Content pipeline PostProcessModules automatically.
• cookies-notice.html — Embedded resource containing the banner HTML/JS. Uses {{COOKIE_NAME}}, {{COOKIE_MESSAGE}}, {{COOKIE_BUTTON_TEXT}}, and {{COOKIE_STYLE}} as substitution tokens, keeping markup editable independently of C# code.
• cookies-notice.css — Embedded resource containing the banner styles, injected at runtime via the {{COOKIE_STYLE}} placeholder in the HTML template.

Configuration (appsettings.json)

All keys are optional with sensible defaults:

{
  "CookiesNoticeName": "cookiesAccepted",
  "CookiesNoticeMessage": "This website uses Google Analytics, and its cookies.",
  "CookiesNoticeButtonText": "Understood"
}

The banner is hidden on load; cookies.js (jsDelivr CDN, pinned @1.0.0) checks for the named cookie on DOMContentLoaded and shows the banner if absent. Clicking the button sets a non-expiring cookie and hides the banner.

@copilot extract the style into a css file

Done in 5537df8. The CSS rules have been moved from cookies-notice.html into a new cookies-notice.css embedded resource. The HTML template now uses a {{COOKIE_STYLE}} placeholder that CookiesNoticeModule fills at runtime by loading the CSS resource via a shared LoadEmbeddedResource helper.
