chore: migrate to Bun, update deps and add Nuxt Fonts

- Replace pnpm with Bun (bun.lock, remove pnpm-lock.yaml)
- Add @nuxt/fonts module and configure Iconify icons
- Add NUXT_OG_IMAGE_SECRET for multi-instance OG image signing
- Update dependencies to latest versions
- Simplify Tailwind font configuration
- Add trustedDependencies and overrides for unhead packages
