[Initiative] gitstore-admin: Commerce operations console

[juliuskrah]

Summary

Build gitstore-admin as an optional commerce admin and operator console for business users and technical users. The console should support catalog operations, authenticated administration, operational diagnostics, and configuration workflows through gitstore-api.

Scope

• Application shell, navigation, and layout system for repeated admin workflows.
• Live GraphQL operations and codegen aligned with the GitStore resource schema.
• Authenticated session handling, route guards, and namespace/repository/store context switching.
• Catalog, media, inventory, pricing, order, checkout, basket, customer, profile, settings, permissions, diagnostics, and configuration surfaces.
• Compatibility coverage for unit, component, codegen, build, and Playwright workflows.

Acceptance criteria

• Child issues define observable UI behavior, live GraphQL integration, loading/error/empty states, and tests for each admin capability.
• Project metadata tracks all work in GitStore Roadmap with Status=Todo, functional Area, and Priority.
• Native GitHub sub-issue and dependency relationships represent the initiative structure and blockers.

Architecture note

gitstore-admin remains an optional add-on and consumes gitstore-api; it must not talk directly to gitstore-git-service.
