[To dev/1.3] Fix subscription topic authorization bypass (#18418)

[Caideyipi]

Summary

• bind subscription authorization to the authenticated RPC session user instead of the client-provided consumer username
• enforce READ_DATA for tree-model topics before subscribe, heartbeat, and polling operations
• recheck authorization on each operation so revoked privileges take effect immediately
• backport of Fix subscription topic authorization bypass #18418 (bc5b6a2d162fa1f38c0553fe177430629bf55262), adapted to the tree-model APIs in dev/1.3
