Subject: [PATCH 7/7] fix(tailor): expand diff scope and preserve casing (fixes
 #805)

Allow AI Tailor to modify more resume sections while preserving
original capitalization:

Backend:
- improver.py: extend _ALLOWED_PATH_PATTERNS with education.description,
  additional.languages, certificationsTraining, awards
- improver.py: refine _is_path_blocked to allow education[i].description
  while keeping degree/institution/years blocked
- improver.py: extend calculate_resume_diff to compare education
  descriptions, languages, and awards
- templates.py: add new PATHS to DIFF_IMPROVE_PROMPT + casing rule
- test_apply_diffs.py: add tests for new allowed/blocked paths

Frontend:
- resume_previewer_context.tsx: expand field_type union with
  'language' | 'award'
- diff-preview-modal.tsx: add ChangeSection rendering for languages
  and awards
