feat : sélecteur d'année dans le calendrier (3ᵉ niveau) (#83)

## Sélecteur d'année dans le calendrier (3ᵉ niveau de navigation)

Ajoute un 3ᵉ niveau de navigation à la famille de composants date, et corrige le bornage min/max du sélecteur de mois.

### Comportement
- Clic sur le champ → calendrier (vue **jours**)
- Clic sur l'en-tête → **sélecteur de mois**
- **Re-clic sur l'en-tête → sélecteur d'année** (grille de 12 ans, chevrons paginant par pas de 12 ans, fenêtre centrée sur l'année courante − 5)
- Clic sur une année → retour au sélecteur de mois ; clic sur un mois → retour à la grille de jours
- Les props `min`/`max` **grisent les mois ET les années** hors plage (corrige l'asymétrie : le `MonthPicker` affichait jusqu'ici tous les mois)

En-tête contextuel : « Mai 2026 » (jours) / « 2026 » (mois) / « 2020 – 2031 » (années).

### Périmètre
- Shell partagé `internal/CalendarField.vue` → bénéficie aux 4 composants publics `Date`, `DateRange`, `DateTime`, `DateWeek`
- **Aucune API publique modifiée**
- Nouveau composant `internal/YearPicker.vue` (calqué sur `MonthPicker`)
- Helpers purs `isMonthInRange` / `isYearInRange` (comparaison par préfixe ISO, bornes inclusives)
- State machine `viewMode` à 3 niveaux (`useCalendarPopover` / `useCalendarView`)

### Tests
- Suite date **246/246 verte**, ESLint propre
- Unitaires : helpers, `YearPicker`, `MonthPicker` (grisage), composables (pagination ±12, recentrage, `selectYear`)
- e2e `Date.test.ts` : flux complet jours→mois→années→mois→jours + grisage min/max

### Process
Développé en brainstorming → spec → plan → exécution TDD (un commit par étape). Spec et plan inclus sous `docs/superpowers/`.
