fix: enhance back navigation in NotFoundPage component and remove unused deps (#9341)

* fix: enhance back navigation in NotFoundPage component

* chore: update dependencies and refactor imports

- Updated `framer-motion` to version `12.23.12` in `package.json` and `bun.lock`.
- Removed unused dependencies: `fuse.js`, `react-code-blocks`, `react-datepicker`, `pocketbase`, `simple-icons`.
- Refactored import in `number-ticker.tsx` to use `motion/react` instead of `framer-motion`.
- Removed CSS import for `react-datepicker` in `page.tsx`.

* fix: update NotFoundPage redirection to use basePath from site-config

- Modified the redirection logic in NotFoundPage to use the basePath variable.
- Set default basePath to "ProxmoxVE" in site-config for improved routing consistency.

* update bun.lock
