refactor: extract Icons and InlineFormActions UI components

- Add Icons.tsx: IconEdit, IconTrash, IconDuplicate, IconPlus, IconCheck, IconClose
- Add InlineFormActions.tsx: unified Annuler/Ajouter-Enregistrer button pair
- Replace inline SVGs in SwotCard, YearReviewCard, WeeklyCheckInCard, SwotQuadrant,
  YearReviewSection, WeeklyCheckInSection, EditableTitle, Modal, GifMoodCard
