[BUG] Can't create library using media from mounted read-only volume outside /data path

[miasma13]

Description of the Bug

When running via Docker container on Synology NAS when I can specify and mount additional paths to the container.
If the new path is outside the base /data path the attempt to create a new library using that path fails.

Expected Behavior

Library is created using media from mounted path.

To Reproduce

Steps to reproduce the behavior:

1. Mount new media path in the Docker container settings that is outside /data path
2. Start Stump container
3. Create new library selecting the new path
4. Error occurs: "A critical error occurred
   Minified React error TypeScript type generation #31; visit https://reactjs.org/docs/error-decoder.html?invariant=31&args[]=object%20with%20keys%20%7Bstatus%2C%20message%7D for the full message or use the non-minified dev environment for full errors and additional helpful warnings."

Environment:

• Docker container on Synology NAS

Build Details:

• Version: 0.0.9
• Docker: yes

Additional context

I would like to create a new Stump library at a mounted preexisting path with read-only permission (without the need to change paths ownership)
