feat: enhance ESLint configuration and improve component error handling

- Updated ESLint configuration to include support for `.mjs` and `.cjs` file types, adding necessary global variables for Node.js and browser environments.
- Introduced a new `vite-env.d.ts` file to define environment variables for Vite, improving type safety.
- Refactored error handling in `file-browser-dialog.tsx`, `description-image-dropzone.tsx`, and `feature-image-upload.tsx` to omit error parameters, simplifying the catch blocks.
- Removed unused bug report button functionality from the sidebar, streamlining the component structure.
- Adjusted various components to improve code readability and maintainability, including updates to type imports and component props.

These changes aim to enhance the development experience by improving linting support and simplifying error handling across components.
