[Phase 3A]: Add dashboard UI scaffold and components (feature/dashboard-ui)

[Vaibosnikov]

This PR adds the dashboard UI scaffold for TestCraft under runner/web. It provides the UI shell, basic layout, and components to be used by the frontend team:

Included:

• React + Vite + Tailwind setup
• UI Shell: Sidebar, Header
• Dashboard page: Summary cards and Runs table
• Components: RunsTable, SummaryCard
• Local mock data: src/mock/sampleRuns.json (for UI development without backend)
• README with run instructions

Notes:

• This is a UI-only branch (no backend integration). Use mock data for development.
• Integration to the backend will be handled in feature/dashboard-integration (fetching /v1/runs and /v1/tests).

Dashboard UI — Branch Summary (feature/dashboard-ui)

This branch introduces the complete UI scaffold for the TestCraft Dashboard so that our frontend
work can start independently of backend integration.

Work Completed

• Added a dedicated React + Vite + Tailwind project under runner/web
• Implemented base layout:
  • Sidebar navigation
  • Top header bar
  • Application shell structure
• Added core dashboard components:
  • SummaryCard (stats)
  • RunsTable (recent run history)
• Added initial DashboardPage with mock data loading
• Included mock JSON dataset (sampleRuns.json) to allow UI development without backend dependency
• Fully functional development server now running at: http://localhost:5173/

Purpose

This creates the foundation for:

• UI development by the frontend team
• Dashboard visualizations in the next branch
• Backend API integration in feature/dashboard-integration

Notes for Reviewers

• This is a UI-only branch — all data shown comes from mock JSON files.
• Backend API integration will be added in a later branch.
• Feel free to review component structure, naming, and layout responsiveness.
• Screenshots have been attached below for faculty reference.
