feat(use-blade): expose activeChildParam for active-row highlighting

[maksimzinchuk]

Summary

Adds activeChildParam to useBlade() — a computed of the param of the direct child blade currently open from this blade (or undefined).

This lets a list blade highlight the row whose details blade is open, without manually tracking the open child. It is reactive over the blade stack and reload-safe: on reload the child blade is restored with its param, so the highlight is too.

const { activeChildParam } = useBlade();
// <VcDataTable :active-item-id="activeChildParam" ... />

Test Plan

• yarn typecheck
• vitest — useBlade.test.ts (28 tests, incl. new activeChildParam cases)
• yarn docs:lint — 0 errors
• eslint / prettier on changed files — clean

Notes

• Independent of the single-load-restore PR (feat(vc-data-table): single-load restore for list views #242); both branch from main.
• Consumed by the vendor-portal modularity-migration branch (offers/orders/products/team/videos/etc. list pages bind :active-item-id="activeChildParam").
