added media permissions (#142)

* added permissions support for media module

introduced `MediaPermissions` for fine-grained access control in the media module, updated routes to enforce these permissions, and adjusted permission registration logic.

* fix: handle token absence in getUploadHeaders and add tests for transport modes

ensure getUploadHeaders does not set Authorization header when token is missing. Add unit tests to validate behavior for different token_transport options.

* remove console.log on DropzoneContainer.tsx
