fix(web): Create Person face preview not working for video assets

FaceEditor previously required an HTMLImageElement | HTMLVideoElement prop to
compute layout metrics and generate the face crop preview. This was unavailable
for video assets, so the preview thumbnail in the Create Person modal was always
missing, and face positions could be NaN during image load (naturalWidth is 0
before the image decodes).

Replace the DOM element prop with assetSize: Size and containerSize: Size, using
asset metadata dimensions that are always available from the API response.
computeContentMetrics() is extracted as a pure utility alongside
mapContentRectToNatural() for converting face rect coordinates back to original
image space.

For videos, VideoNativeViewer now captures the current frame to canvas when face
edit mode opens and sets assetViewerManager.imgRef, giving FaceEditor the same
image-based preview path as photo assets.

-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in

-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior
-deemed unprofessional or unwelcome in the community.
-

-providing clarity around the nature of the violation and an
-explanation of why the behavior was inappropriate. A public apology
-may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series
-of actions.
-
-**Consequence**: A warning with consequences for continued
-behavior. No interaction with the people involved, including
-unsolicited interaction with those enforcing the Code of Conduct, for
-a specified period of time. This includes avoiding interactions in
-community spaces as well as external channels like social
-media. Violating these terms may lead to a temporary or permanent ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards,
-including sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or
-public communication with the community for a specified period of
-time. No public or private interaction with the people involved,
-including unsolicited interaction with those enforcing the Code of
-Conduct, is allowed during this period. Violating these terms may lead
-to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of
-community standards, including sustained inappropriate behavior,
