Add a read-only aggregate view per channel: its linked groups and a deterministic wildcard-free supported-model list with pricing details. Backend - service.Channel.SupportedModels(): combine ModelMapping keys with same-platform ModelPricing.Models; trailing "*" keys expand via pricing prefix match; platforms without a mapping produce no entries (intentional "no mapping = not shown" rule). - Extract splitWildcardSuffix() shared with toModelEntry. - Build a per-call pricing lookup map (platform+lowerName -> *pricing) to avoid O(N*M) scans in SupportedModels. - ChannelService.ListAvailable() aggregates channels + active groups; filters out group IDs no longer active. - Admin route GET /api/v1/admin/channels/available returns the full DTO (id, status, billing_model_source, restrict_models, groups, supported_models). - User route GET /api/v1/channels/available applies three filters: Status==active, visible-group intersection, and platform filter on supported_models (prevents cross-platform leak when a channel links to both a user-accessible group and an inaccessible one on another platform). Response is a plain array (matches the /groups/available sibling shape). Field whitelist omits billing_model_source, restrict_models, ids, status, sort_order. Frontend - New /admin/available-channels and /available-channels views backed by a shared AvailableChannelsTable component (admin adds status + billing-source columns via slots). - PricingRow extracted to its own SFC; SupportedModelChip references shared billing-mode constants in constants/channel.ts. - Sidebar: new entry above "渠道管理" for admin; matching entry in user nav. - i18n: zh + en coverage for both namespaces. Tests - SupportedModels: wildcard-only pricing skipped, prefix-matches- nothing, cross-platform bleed, case-insensitive dedup, empty platform mapping. - ListAvailable: nil groupRepo, inactive-group-ID dropped, stable case-insensitive name sort. - User handler: 401 on unauthenticated, visible-group intersection, platform filter on supported_models, JSON whitelist. - Admin handler: full DTO including default BillingModelSource fallback.
