feat: validator cache eviction — cap at 500K entries, evict oldest 10% by resolve_time master

prevents unbounded memory growth from caching every DID's signing key. configurable via VALIDATOR_CACHE_SIZE env var. eviction runs in the background resolve loop (not the hot validation path). adds relay_validator_cache_evictions_total prometheus counter.
