 * ModelsFetcherImpl - Implementation with multi-level caching.

 * Caching strategy:
 * 1. Plugin models are cached per tenant (with access control applied by PluginModelsProvider)
 * 2. Database models are cached per tenant (raw from DB)
 * 3. Filtered database models are cached per tenant + identity (with access control applied)
 * 4. Final merged list is cached per tenant + identity
