feat(sentinel): deduplicate metrics push processing

Move Sentinel push handling into a controller and dispatch server update jobs only when container state changes or the force interval elapses. Add opt-in PostgreSQL read/write replica configuration and tune periodic proxy network and storage checks to reduce unnecessary work.

Add feature coverage for replica config, Sentinel push deduplication, deployment log scrolling, and server update job optimizations.
