fix(health): bound remote lock online checks (#6737)

Browse Source 
Keep /health/ready from riding the generic internode lock RPC and channel keepalive budgets when a peer host is unreachable. Add a health-specific lock online timeout, route ping failures through the existing remote lock RPC eviction path, cache the static ping payload for readiness fan-out, and cover hanging cached channels with focused tests.
