I would like to allow a given user (or all users) to have unlimited storage. In Monica 4.x I believe this was achieved by setting the limit to "0" which was interpreted as infinite, but when I do that in 5.x I get:

Describe the solution you'd like

So long as we're inventing a new amount, I'd suggest that setting the storage limit to -1 should result in no limit. That way if someone truly doesn't want to allow any form of upload they could use 0 for that purpose.

Describe alternatives you've considered (optional)
An alternative that is possible now would be to set an incredibly high number for the limit. It'd be nice to have something more explicit, though.

Additional context

I haven't verified if this works, but the .env.example file does say that 0=unlimited:

monica/.env.example

Line 100 in c8874d4

# 0 = unlimited

@pingiun right -- the screen shot is showing what I see when I have the limit set to 0.

I believe v5 doesn't honor it in the same way as v4.
