Restore PHP 8.3 compatibility and remove build-time external font dependency

[Copilot]

This change addresses two environment-level breakages in the app: Composer could not resolve dependencies on PHP 8.3, and Vite production builds depended on fetching Bunny-hosted fonts at build time. The result is a repository that resolves dependencies and builds without those external constraints.

• Dependency compatibility

  • Removed the unused pushery/wirekit package, which was the only dependency forcing PHP 8.4.
  • Lowered the root PHP constraint from ^8.4 to ^8.3 to match the actual supported framework/runtime set.

• Blade/layout cleanup

  • Removed @wirekitStyles / @wirekitScripts from the app and guest layouts.
  • Removed the Wirekit CSS import from resources/css/app.css.

• Build determinism

  • Removed Bunny font integration from vite.config.js.
  • Removed external Bunny font links from Blade layouts so the app uses the existing local/system font stack instead of a network fetch during build.

• Docs alignment

  • Updated the README to reflect the actual PHP requirement and removed Wirekit from the documented stack.
