chore: remove deprecated files and configurations

- Deleted .gitignore, biome.json, next.config.ts, package.json, pnpm-lock.yaml, pnpm-workspace.yaml, postcss.config.mjs, README.md, and various API, component, and utility files to clean up the codebase.
- Removed unused database files and migration scripts to streamline the project structure.
- Eliminated obsolete hooks and services to enhance maintainability and reduce clutter.
