feat(style-acq T14): שער-יו"ר לאישור הצעות-curator → הטמעה לפרופיל

סוגר את הלולאה מקצה-לקצה (INV-G10/LRN1): ה-curator מציע (status=analyzed),
היו"ר מאשרת, והלקחים נכתבים לערוצים שהכותב צורך (T15) — אין auto-commit.

- db.get_draft_final_pair(id) — שורת-פנקס מלאה כולל analysis.
- app.py: GET /api/learning/pairs/{id} (חושף רק changes מסוג style_method —
  INV-LRN5) + POST .../promote (לקחים→discussion_rules['universal'],
  ביטויים→transition_phrases['universal'] דרך merge ל-appeal_type_rules;
  status→lessons_folded). _append_methodology_override משותף.
- web-ui: usePairDetail/usePromoteLearning + ProposalReview (בחירת לקחים/
  ביטויים לאימוץ) בטאב "למידה" עבור pairs במצב analyzed.

INV-G10 (שער-יו"ר) · INV-LRN1 (אין auto-commit) · INV-LRN5 (טוהר).
