fix(router): give cooldowns their own cache so siblings see a bench in ~1s (#40025)
Cooldown entries rode the router-wide DualCache, which re-reads a key that is
missing from memory at most once every 10s. A deployment benched on one replica
therefore kept taking traffic on its siblings for up to 10 seconds, and the same
shared in-memory tier could evict a live cooldown once 200 unrelated router keys
crowded it out, which sent even the benching replica back to the dead deployment.

CooldownCache now owns a DualCache over the router's Redis with a 1s read
interval and an in-memory tier that only holds cooldown keys. Redis is attached
lazily because the router builds the cooldown cache before it wires Redis up.
