feat: Add support for user uploaded files (#2100)

* feat: add user file upload support for bookmarks

Add a new "user-uploaded" asset type that allows users to upload and
attach their own files to bookmarks from the attachment box in the
bookmark preview page.

Changes:
- Add USER_UPLOADED asset type to database schema
- Add userUploaded to zAssetTypesSchema for type safety
- Update attachment permissions to allow attaching/detaching user files
- Add fileName field to asset schema for displaying custom filenames
- Add "Upload File" button in AttachmentBox component
- Display actual filename for user-uploaded files
- Allow any file type for user uploads (respects existing upload limits)
- Add Upload icon for user-uploaded files

Fixes #1863 related asset attachment improvements

* fix: ensure fileName is returned and remove edit button for user uploads

- Fix attachAsset mutation to fetch and return complete asset with fileName
  instead of just returning the input (which lacks fileName)
- Remove replace/edit button for user-uploaded files - users can only
  delete and re-upload instead
- This ensures the filename displays correctly in the UI immediately
  after upload

Fixes fileName propagation issue for user-uploaded assets

* fix asset file name

* remove filename from attach asset api
