feat(community,feedback): +5 reward chip + Phase 3.F legacy-cleanup

UI:
- FeedbackQuickModal Success-State + Onboarding-Wish Confirm zeigen
  +5-Mana-Reward-Chip mit reward-in-Animation. Sofortiger Sichtbarer
  Reziprozitäts-Loop.

Legacy-Cleanup (Phase 3.F):
- @mana/feedback dropped:
  - FeedbackPage.svelte, FeedbackCard.svelte, FeedbackList.svelte,
    FeedbackForm.svelte, VoteButton.svelte, StatusBadge.svelte
    (alles Pre-Reactions-Markup, durch Community-Modul ersetzt)
  - vote/unvote/toggleVote/getPublicFeedback service-shims
  - VoteResponse, voteCount, userHasVoted Types
- mana-web dropped:
  - lib/modules/feedback/ListView.svelte
  - routes/(app)/feedback/+page.svelte
  - app-registry-Eintrag 'feedback' (nur Bug-Reports — Community macht
    das ohnehin besser via /community)

Pre-launch saubere Lösung: keine Backward-Compat-Shims, keine alten
Markup-Reste. ReactionBar bleibt der einzige Voting-Surface, /community
ist die einzige Feedback-Surface.
