GroupConfig gains CacheTTL (json cacheTTL, empty inherits the global
cache.ttl). Parsed and validated at construction (newAuthStore,
groupCacheTTL in cache.go): a malformed duration, a duration <= 0, or
CacheTTL set while the global cache block is not configured is a
constructor error naming the group, mirroring Cache:true's existing
"nothing to inherit from" check.
group carries the resolved time.Duration (0 means inherit).
responseCache.store gains an explicit ttl parameter; routes_unified.go
computes effectiveTTL(g.cache, grp) immediately before each store call,
so setEx's Redis-native EX seconds reflect the group's own override.
Tests: constructor-error table, empty-inherits and valid-override
resolution, effectiveTTL inheritance/override, a scripted-RESP-server
proof that store's SET...EX carries a different value per group, and an
end-to-end Gateway.ServeHTTP test with two groups asserting the actual
wire EX value (30 vs 60) differs per group.

Spec §5 (v0.2): Config.ModelAliases map[string]string, alias-first
resolution precedence ahead of provider-prefix splitting, alias-OR-target
authorization, lazy target resolution with a 404 naming both ids,
/v1/models listing, admin overview alias table (JSON + dashboard), and
construction-time validation (shape, prefix-shadow, explicit-model
collision, chain, empty target).
routes_unified.go/routes_media.go needed no resolution-call-site changes
- both already pass the client's raw requested id through to
registry.resolve, so aliases inherit the __alias echo and multipart
rewrite machinery for free. cache.go needed no changes either - cacheKey
already hashes requestedModel, so two aliases resolving to the same
target already produce distinct cache entries.
Adds registry_test.go validation table + precedence/authz/lazy-404/
listing coverage, a dedicated cache-key split test, chat/embeddings/
images/audio-transcriptions end-to-end tests, an extended admin overview
test, and an integration test covering the openai-type vs anthropic-type
echo asymmetry under real Traefik+Yaegi.
