feat(backend): Add correctness score to execution activity generation (#11325)

## Summary
Add AI-generated correctness score field to execution activity status
generation to provide quantitative assessment of how well executions
achieved their intended purpose.

## What Changed
- Added `correctness_score` field (float 0.0-1.0) to
`GraphExecutionStats` model
- **REFACTORED**: Removed duplicate `llm_utils.py` and reused existing
`AIStructuredResponseGeneratorBlock` logic
- Updated activity status generator to use structured responses instead
of plain text
- Modified prompts to include correctness assessment with 5-tier scoring
system:
  - 0.0-0.2: Failure
  - 0.2-0.4: Poor 
  - 0.4-0.6: Partial Success
  - 0.6-0.8: Mostly Successful
  - 0.8-1.0: Success
- Updated manager.py to extract and set both activity_status and
correctness_score
- Fixed tests to work with existing structured response interface

## Technical Details
- **Code Reuse**: Eliminated duplication by using existing
`AIStructuredResponseGeneratorBlock` instead of creating new LLM
utilities
- Added JSON validation with retry logic for malformed responses
- Maintained backward compatibility for existing activity status
functionality
- Score is clamped to valid 0.0-1.0 range and validated
- All type errors resolved and linting passes

## Test Plan
- [x] All existing tests pass with refactored structure
- [x] Structured LLM call functionality tested with success and error
cases
- [x] Activity status generation tested with various execution scenarios
- [x] Integration tests verify both fields are properly set in execution
stats
- [x] No code duplication - reuses existing block logic
