enhance: Optimize channel node balancing for uneven QN distribution (#42786) (#43423) 
issue: #42860
pr: #42786
Fix channel node allocation when QueryNode count is not a multiple of
channel count. The previous algorithm used simple division which caused
uneven distribution with remainders.

Key improvements:
- Implement smart remainder distribution algorithm
- Refactor large function into focused helper functions
- Support two-phase rebalancing (release then allocate)
- Handle edge cases like insufficient nodes gracefully
