feat(video3d): bind template slots through the shared asset picker

[IAnMove]

Problem

Template composer used a private Library grid with click-to-confirm and its own pagination. That is not the shared dual-origin picker, and a click confirmed immediately.

Behavior

• TPL-01..08 go through AssetInput / common explorer (workspaceId + remote catalog from feat(assets): page the shared explorer against the catalog API #230).
• Confirm is Choose, not clicking a card.
• Bindings still store durable asset.id. catalogBindingIssue still blocks incompatible items.
• A local file without asset_id is rejected (canonical Library identity required).
• JSON original import is unchanged.

IDs

TPL-01..08

Base / HEAD

origin/development 661d241c (#237).

Tests

templateSlotPick.test.mjs + templateAssetPicker.test.tsx: 6/6. ESLint on touched TS, 0 warnings. E2E composer flow updated to From HocusPocus → Choose.

Limits

Draft until CI. No GPU. Do not merge from this description if you are a bot; human asked to merge after review.

Note

Medium Risk
Changes how Video3D template slots bind to Library assets (shared picker + async commit), which could regress slot assignment or stale bindings if the race guards fail.

Overview
Replaces the template composer’s bespoke Library grid with the shared AssetInput / asset explorer, so slot assignment matches the dual-origin picker used elsewhere (From my computer / From HocusPocus) and confirms with Choose instead of clicking a catalog card.

commitTemplateSlotChoice in templateSlotPick.ts loads the durable catalog id via fetchAsset, ignores stale picks when workspace/slot/generation changes, and rejects local choices without asset_id (new needsCatalogIdentity copy). catalogBindingIssue and provided_only catalog lineage behavior stay the same; the dialog now wires onClear / optional slots through the picker.

Unit, composer, and E2E tests were updated for the explorer flow; the old paginated picker tests were dropped in favor of slot-commit coverage.
