refactor: translate agenticReadiness module from Spanish to English

Complete English translation of the Agentic Readiness scoring module across
frontend and backend codebases to improve code maintainability and international
collaboration.

Frontend changes:
- agenticReadinessV2.ts: Translated all algorithm functions, subfactor names,
  and descriptions to English (repeatability, predictability, structuring,
  inverseComplexity, stability, ROI)
- AgenticReadinessTab.tsx: Translated RED_FLAG_CONFIGS labels and descriptions
- locales/en.json & es.json: Added new translation keys for subfactors with
  both English and Spanish versions

Backend changes:
- agentic_score.py: Translated all docstrings, comments, and reason codes
  from Spanish to English while maintaining API compatibility

All changes tested with successful frontend build compilation (no errors).
