## Summary by CodeRabbit
* **New Features**
* Session versioning added to validate coordinator compatibility during
registration and active takeover.
* **Changes**
* Active–standby flow simplified: standby-to-active activation now
always enabled and initialized unconditionally.
* Registration uses version-aware transactions to ensure version
consistency during takeover.
* Startup/health startup path streamlined.
* **Tests**
* Added version-key integration test; removed test for disabling
active-standby.
* Updated flush test to assert rate-limiter errors occur.
* **Chores**
* Removed centralized connection manager and its test suite.

- the flush rate is modified into 4qps, so the testcase is fail.
___
### **PR Type**
Tests, Bug fix
___
### **Description**
- Replace sequential flush calls with concurrent requests to trigger
rate limiting
- Add sync.WaitGroup for concurrent goroutine execution
- Check for rate limit errors across multiple concurrent flush
operations
- Remove hardcoded error message expectation for flexibility
