feat: Import from Files works, remove pipeline button from files page

- Import from Files now navigates back to the tool page with the
  selected file loaded (uses selectForTool router state)
- Tool page skips file store reset when arriving from the library
- Removed "Open in Pipeline" button from file details and file list
- Button text changes to "Select File" when in file-selection mode
