Complete the DoubaoVideo asset library integration on top of the
managed per-user asset groups:
- Asset endpoint resolution is an explicit three-level priority: a
hard-coded override wins, otherwise the per-channel credential
base_url from channel_asset_credentials is used verbatim (it already
contains the full /openApi/portrait path), otherwise the official
default. The channel video base URL no longer participates in asset
routing, so video (official Ark) and asset (gateway) addresses stay
fully independent. The channel form gains an "素材 API 地址" field with
a hint that the official address has no asset API, and the channel
type label becomes "豆包视频（素材网关）" to surface the split. Credential
summaries now cover DoubaoVideo channels and echo the base URL back
for editing.
- After an asset request auto-matches a channel (no existing user
binding), persist it to user_asset_channels so subsequent asset and
video requests stay on the same channel, keeping asset:// references
consistent with the upload channel. This mirrors the video-task
binding backfill; binding failure logs a warning and does not fail
the asset operation.

Register a DoubaoVideo asset adapter that forwards the Ark-compatible
asset API (POST /api/v1/volcengine/asset?Action=xx) to the official
/openApi/portrait endpoint with a Volcengine V4 HMAC-SHA256 signature
(canonical request over content-type/host/x-content-sha256/x-date,
date/cn-beijing/ark/request scope). The AK/SK pair and optional
project code are stored in channel_asset_credentials (pool_id holds
the project code), so asset credentials stay separate from the video
Bearer key; the channel form now accepts them for type 54.
DoubaoVideo joins the seedance asset family so a user's asset upload
channel and video task channel stay the same (asset:// references
pass through to the upstream). Both resolution chains (asset proxy
resolver and video asset family matcher) now require the asset
credential to be configured before a type-54 channel can serve,
bind, or be auto-matched for assets, falling through to compatible
channels otherwise. The /api/v3 native-path whitelist simplifies
back to the family list now that 54 is a member.
Verified end-to-end against the real upstream: CreateAssetGroup,
CreateAsset (real video upload, Processing -> Active moderation),
ListAssets/GetAsset, and a video generation task referencing the
asset via asset://video reference (succeeded, 432900 tokens).

Add a new /api/user/channels endpoint that returns only enabled channels
with non-sensitive fields (id, name, type, remark) for token channel binding.
Update EditTokenModal to use this endpoint and display remark instead of ID
in the channel dropdown.
