* Integration pages from Notion
* fix integration page
* Refactor environment variables and update routing in integration pages
- Removed unused environment variables related to MUX from `.env.docker` and `.env.example` to streamline configuration.
- Updated routing links in `OpenFormFooter.vue` to correct navigation paths for "Integrations", "Report Abuse", and "Privacy Policy", enhancing user experience.
- Added middleware to `definePageMeta` in `index.vue` and `[slug].vue` for integration pages to enforce self-hosted logic.
These changes aim to improve code clarity and ensure proper routing functionality across the application.
