* modify MediaApi to support custom fetch implementation, defaults to native fetch
added an optional `fetcher` parameter to allow usage of a custom fetch function in both `upload` and `fetcher` methods. Defaults to the standard `fetch` if none is provided.
* fix tests and improve api fetcher types
* 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
