Fixes #6479 ## What does this PR do? This PR fixes stale discovery upstream data remaining in the gateway after a selector is deleted. The main changes are: - propagate discovery upstream DELETE events through path-based sync; - handle ZooKeeper node deletion events correctly; - reconcile HTTP discovery upstream snapshots so removed selectors are unsubscribed; - forward upstream removal events to plugin handlers; - remove stale upstream state from Divide, WebSocket, gRPC, and TCP plugins; - add TCP selector id-to-name mapping for deletion handling; - validate plugin names before publishing discovery upstream removal events from Admin. ## Why is this needed? Before this change, discovery upstream deletion was not fully propagated through several sync paths. As a result, deleted discovery upstreams could remain in gateway-side runtime caches and continue to affect routing. ## Tests Added or updated tests for: - path-based discovery upstream deletion; - ZooKeeper delete event propagation; - HTTP snapshot deletion reconciliation; - plugin upstream cache removal; - TCP selector id/name resolution and cleanup; - gRPC cache/client invalidation.
