feat: Part product images + seasonal tire-swap reminders

Part (HasMedia):
- Spatie media `image` single-file collection + imageUrl() helper
- PartResource form: image upload section (image editor, 2 MB max)
- Parts list: circular thumbnail column
- Shop catalog cards: square thumbnail + 📦 placeholder
- Shop part detail: 260px image alongside info, single column when no image

Seasonal tire-swap reminders:
- NotificationDispatcher::tireSeasonalSwap(TireSet) — Telegram first, email
  fallback (when set has a vehicle, via ServiceReminderMail with 'tire_swap'
  type and a size-aware note)
- tires:remind-seasonal artisan command, self-gating to Feb 15-Mar 15
  (notify winter sets stored) and Sep 15-Oct 15 (notify summer sets stored).
  60-day cooldown per client via service_reminders_sent. --force / --dry-run.
- Schedule: weekly Mon 09:30

Tests (6 new):
- outside window no-ops; spring window notifies winter; spring ignores summer;
  autumn notifies summer; cooldown blocks doubles; --force overrides window

Full suite: 106 passed.
