Bug: Files Route validation can lead to breakage due to missing reserved route

[zoeyronain]

Bug description

I was trying to change my generated upload URLs from /u to /r and thought that was the place where I would change it. When you try to click save with it set to /raw it says "Provided route is reserved" but it happily let me save with it set to /r. Zipline continued to work fine until I had to restart the container it lives in and it failed. Going into the Postgresql database and setting filesRoute back to /u thankfully fixed it.

Shouldn't /r also be added to the protected paths due to this?

(I wound up adding a sed command in my upload script to switch the route out before the URL copies to my clipboard in the end. Also I build from source because Docker containers in Proxmox are a bit touchy)

How is Zipline being run?

Built from source (running it through pnpm start or node, etc.)

Zipline Version

yea, /r/ was added some time into v4 as v3 used to use /r/ while v4 now uses /raw/ so it was just added as a backwards compatibility thing. fixed ce8b3ed
