[feature] persist the timing state of media-cleanup-every

[cdn0x12]

Is your feature request related to a problem ?

It seems that the timer for media-cleanup-every get reset every time a gotosocial instance restarts. If this is true, it means that the media auto-cleanup will never take effect if the value of media-cleanup-every is greater than the interval at which the user update their GTS instance.

Is it possible to save the timer for media-cleanup-every, so that the GTS instance can have the media-cleanup-every interval set freely even in the case of frequent updates?

p.s. will #3042 fix this issue?

Describe the solution you'd like.

Persist the timing state of media-cleanup-every to db.

Describe alternatives you've considered.

It would also be helpful to add a corresponding note in the documentation.

Additional context.

Specifically, my GTS instance restarts approximately every 24 hours due to updates. After setting media-cleanup-every to 168h, my storage keeps increasing and seems to never be cleaned up.

Just realized this is a duplicate of #2492, so I'll close this one. In the meantime, perhaps you could try just restarting GtS once every 8 days or so, to ensure the media cleanup runs, that would at least prevent your media size from getting out of control while we figure something out for storing the timing of jobs.

Thanks, Will follow #2492 then :)
