Move auth routes to server/api/auth/

BREAKING CHANGE: Auth routes moved from /auth/* to /api/auth/*

- Move server/routes/auth/ to server/api/auth/
- Update login.vue to use /api/auth/authentik
- Update UserMenu.vue to use /api/auth/logout
- Remove old server/routes/ structure
- server/api/ is better supported in Nuxt 4

IMPORTANT: Update these in Gitea:
- Variable NUXT_OAUTH_AUTHENTIK_REDIRECT_URL to: https://seguidordelotes.nucleoriofrio.com/api/auth/authentik
- Update Authentik redirect URI to: https://seguidordelotes.nucleoriofrio.com/api/auth/authentik
