Add anti-raid and anti-nuke protection

Join Gate (account age, avatar, advertising and username filters, bot
checks), raid detection with invite pausing, anti-nuke quarantine of
admins who mass delete, manual and automatic lockdowns, a decaying heat
score against spam, role and channel snapshots with restore, and alert
DMs to the owner and trusted users. Everything that weakens protection
is limited to the owner and the trusted list.
