Is your feature request related to a problem? Please describe.
Currently, the web interface always lists folders before files, regardless of the sort mode. This behavior can be counterintuitive for users who prefer a flat alphabetical listing of all items (folders and files mixed by name).

Describe the solution you'd like
An option (e.g., a toggle or user preference) to sort folders and files together by name in the "Name" sorting mode, similar to some modern file managers or web-based UIs.

Describe alternatives you've considered

• Using WebDAV or desktop clients that support mixed sorting (not ideal for all users).
• Forking the frontend and patching the behavior (not maintainable for long term).

Additional context
This feature would improve consistency and usability for users expecting flat alphabetical order in the file view.

Thanks for considering this improvement!
