feat(feedback): public feed types + ReactionBar + service split

@mana/feedback wird zur Pflege-SSOT für Public-Community-Hub.

- PublicFeedbackItem-Typ: anonymisiertes Item, das nur display_name +
  reactions + status führt — kein userId, displayHash, deviceInfo.
- ReactionEmoji ('👍' '❤️' '🚀' '🤔' '🎉') + REACTION_LABELS mit DE-Labels.
- CreateFeedbackInput erweitert um moduleContext + parentId. Reactions
  + score auf Feedback-Type optional gemacht.
- Service-Split:
  createFeedbackService    — auth-required Submit/React/Manage,
                            getPublicFeed (auth-enriched mit myReactions)
  createPublicFeedbackService — anonymous, SSR-only, getFeed/getItem.
  toggleReaction(emoji) statt vote/unvote (legacy-Shims bleiben für
  back-compat zu vote → '👍'-Toggle).
- ReactionBar.svelte: Slack-Style emoji-row mit Active-Highlighting für
  myReactions, ReadOnly-Mode für Public-SSR. Auto-disabled-Tooltip.
- index.ts re-exportiert die neuen Typen + ReactionBar; FeedbackVote
  rausgeschmissen (durch FeedbackReactions im Server-Schema ersetzt).

FeedbackCard + FeedbackPage minimal angepasst, damit svelte-check
clean bleibt — die Legacy-Komponenten bleiben funktional, werden aber
in Phase 3 zu @mana/feedback's neuen Modul-Views ausgemistet.
