feat: clean tool page nav, add Import from Files on dropzone

- Removed Automate/Editor/Files links from top nav on tool pages,
  keeping only the breadcrumb + help + avatar for a cleaner look
- Added "Import from Files" link on the tool dropzone that navigates
  to the file library, letting users import previously processed files
