// ============================================================================
//
// Video generation channels (OpenAI Sora /v1/videos, OpenAI-compatible video
// gateway /v1/videos/generations, etc.) are submitted via the task framework
// and historically only supported per-call pricing through ModelPriceHelperPerCall.
//
// ModelPriceHelperVideo extends that with optional token-based pricing using
// VideoRatio / VideoCompletionRatio, so admins who prefer "$/1M token" semantics
// can configure the per-second/per-resolution cost via ratios instead of a
// flat per-video price.
//
// Selection rules (highest priority first), aligned with the ratio UI
// 「按 token 计费 / 按视频计费」:
//
//  1. Token-based pricing when tryVideoTokenPriceData succeeds (VideoRatio /
//     resolution token_price rules + ModelRatio). Takes precedence over
//     per-call ModelPrice / VideoPrice so admins who choose per-token in the
//     console are not overridden by legacy fixed prices.
//
//  2. Per-resolution flat price per video (*_per_video tables), then
//
//  3. Any other per-call tier (supplier ModelPrice, group ModelPrice, VideoPrice,
//     ChannelVideoPrice) -> ModelPriceHelperPerCall (OtherRatios from adaptor).
//
//  4. Nothing matched -> ModelPriceHelperPerCall fallback (error or default).
