[Feature Request] Automatic flush of expired temporary rules (after a period)

[BetweenTheKeyboardAndChair]

I'd like temporary rules, e.g. block/allow for 5 minutes, to be automatically deleted after a specified period.

The behavior and UI could be similar to the automatic flushing of events after N days.

(I asked for this in another conversation quite a while back. I don't think it ever got its own feature request.)

Thank you @BetweenTheKeyboardAndChair , I looked for this request but I didn't find it, so I only added more options to discard temporary rules.

The new option could be:

[x] Delete temporary rules: [ 5m or less ]
[x] After                           +[ 2 ]- days.

That looks good. Thank you.
