FEATURE: Penalty history improvements (#13359)

* FEATURE: add penalty history when silencing a user

Display penalty history (last 6 months) when silencing/suspending a user

* FEATURE: allow default penalty values to be chosen

Adds a site setting that designates default penalty values in hours.

Silence/suspend modals will auto-fill in the default values, but otherwise
will still allow moderators to pick and overwrite values as normal.

First silence/suspend: first value
Second silence/suspend: second value
etc.

Penalty counts are forgiven at the same rate as tl3 promotion requirements do.
