feat(community): Phase 3.B — loop closure (notifications + my-wishes page)

Schließt den Loop zwischen Submit und Ship. User kriegt jetzt:
- Toast beim nächsten App-Start, wenn ein eigener oder unterstützter
  Wisch ›planned/in_progress/completed/declined‹ wurde
- /profile/my-wishes als persönliche Roadmap mit drei Tabs:
  Eigene · Unterstützt · Inbox

Server (mana-analytics):
- Neue Tabelle feedback_notifications mit ON DELETE CASCADE auf
  user_feedback. Migration 0004 lokal + prod eingespielt.
- adminUpdate enqueued bei jeder Status-Transition Author-
  Notifications. AdminResponse-Edits feuern eine eigene
  'admin_response'-Notify. tryGrantShipBonus hängt zusätzlich
  Reactioner-Notifications dran (›Dein Like ist gelandet, +25 Mana‹).
- Endpoints:
    GET  /api/v1/feedback/me/notifications?unread_only=true&limit=N
    POST /api/v1/feedback/me/notifications/:id/read
    POST /api/v1/feedback/me/notifications/read-all
    GET  /api/v1/feedback/me/reacted    (für die My-Wishes-Page)

Package (@mana/feedback):
- FeedbackNotification + NotificationKind types exportiert
- service.getNotifications/markNotificationRead/markAllNotificationsRead
- service.getMyReactedItems

Web:
- lib/notifications/feedback-toaster.svelte.ts: Boot-Pull + 60s-Poll,
  rendert unread-notifications via toast-store, markiert sofort read.
  In (app)/+layout.svelte's authReady-Hook gestartet/gestoppt.
- /profile/my-wishes: Tab-View über getMyFeedback + getMyReactedItems
  + getNotifications. Tabs zeigen Counter-Badges, unread-Badge in der
  Inbox-Sektion. ›Alle als gelesen markieren‹-Action vorhanden.

Pre-launch saubere Lösung — kein Polling-Spam (60s), Mark-Read direkt
nach Toast-Display, fail-soft an mehreren Stellen.
