BotServ: KICK <#channel> TEST <message> dry-run

Browse source 
Reports which content kicker (caps/formatting/badwords) a line would trip,
without kicking anyone — so an op can tune caps% or a badword regex safely.
Reuses the typed KickerSettings::violation() and the shared badword-set
builder (moved to db so the test and the live path share it).
