fix: presence ring shape mismatch, edit history (no text) on E2EE, reaction count

- PresenceRingAvatar: replace circular wrapper div (borderRadius 50%) with
  React.cloneElement injecting outline+outlineOffset directly onto the child
  Avatar element — outline follows the child's actual border-radius so the
  ring matches the avatar shape in every context

- EditHistoryModal: use getClearContent() for the Original entry instead of
  evt.event.content, which is still the ciphertext for E2EE messages and has
  no body field. getClearContent() returns decrypted content bypassing the
  _replacingEvent chain, fixing the "(no text)" shown for encrypted originals

- MessageQuickReactions: 5 → 3 emoji (toolbar too wide with 5)
