feat: bypass !ask cooldown for users with power level >= 50

Add is_elevated() helper that reads the room power level from the nio
client store. Users at PL50+ (Nerdy Council and above) skip the cooldown
check entirely. The timestamp is still recorded so cooldown applies
if their power level is later reduced below 50.
