Add T34 (priority scheduling) + T35: mode 3 — POST /api/dance/upload-character

T34: priorityInbox (M.8) — paid_boost clips get inserted immediately after whatever's currently playing (danceSchedule[0]), pushing every later entry's timing back, rather than waiting for the fill-loop's normal "top up to 30s ahead" trigger. That distinction mattered: draining priorityInbox only from inside the fill loop (first attempt) technically satisfied "never loses to a vote-ranked pick" but could leave a ready paid_boost clip waiting a long time if the schedule already had ~30s queued — dance-mode3.test.js's race test caught this (timed out) before the eager-insert fix. ensureDanceSchedule's existing "generating -> done" reconciliation loop diverts a job into priorityInbox instead of danceQueue's "ready" state when job.priority === "paid_boost", spliced out of danceQueue after the loop (not mid-iteration). T35: POST /api/dance/upload-character (需登录+emailVerified, same rule as T27).

Garment is optional (need求文档 3.3 第 4 点): given garmentId is validated active-or-400, otherwise a random active garment is picked — a fully empty wardrobe is a 400 before any spend. dance-mode3.test.js covers both: auth/balance/no-active-garments gates, the happy path (cost scales with requested segments, character record shape, clip carries priority/requestedByUserId), and T34's actual guarantee — a paid_boost character is scheduled at or ahead of an already-ready free pick for the same garment, distinguished by characterId since both target the same garment on purpose.
