Round system redesign: criteria voting, audience voting, pipeline view, and admin UX improvements

- Schema: Extend LiveVotingSession with votingMode, criteriaJson, audience fields;
  add AudienceVoter model; make LiveVote.userId nullable for audience voters
- Backend: Criteria-based voting with weighted scores, audience registration/voting
  with token-based dedup, configurable jury/audience weight in results
- Jury UI: Criteria scoring with per-criterion sliders alongside simple 1-10 mode
- Public audience voting page at /vote/[sessionId] with mobile-first design
- Admin live voting: Tabbed layout (Session/Config/Results), criteria config,
  audience settings, weight-adjustable results with tie detection
- Round type settings: Visual card selector replacing dropdown, feature tags
- Round detail page: Live event status section, type-specific stats and actions
- Round pipeline view: Horizontal visualization with bottleneck detection,
  List/Pipeline toggle on rounds page
- SSE: Separate jury/audience vote events, audience vote tracking
- Field visibility: Hide irrelevant fields per round type in create/edit forms
