Expand README with repository description and GitHub Actions workflow documentation

[Copilot]

The README lacked context about the repository's purpose and how the CI/CD pipeline operates.

Added comprehensive documentation:

• Repository overview: Clarified this is an internal PowerOffice repository hosting interactive API documentation using React + Swagger UI, deployed to Azure Static Web Apps

• GitHub Actions workflow breakdown:

  • Triggers: Push to main/dev/staging branches and PRs to main
  • Build pipeline: Schema name simplification → npm install/ci → Vite build → Azure deployment
  • Explained the SimplifySchemaNames.cjs preprocessing step that transforms verbose .NET type names in OpenAPI specs
  • PR preview deployments and cleanup on close

• Local development: Setup instructions, build commands, and preview workflow

• Contributing workflow: Branch strategy and deployment targets for internal team members

Key technical detail: The workflow runs a preprocessing step (node ./openapi/SimplifySchemaNames.cjs) before build to strip unnecessary .NET assembly metadata from OpenAPI schema references, improving documentation readability.
