Subject: [PATCH] refactor: migrate to FastEndpoints framework
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ARCHITECTURE CHANGE:
- Replaced ASP.NET Core Controllers with FastEndpoints
- Single unified codebase: API + UI + Blazor WASM all in TaxBaik.Web
- FastEndpoints provides:
  * Convention-based routing (no attribute decorators)
  * Built-in validation (FluentValidation)
  * Better request/response mapping
  * Cleaner dependency injection

Program.cs:
- AddControllers() → AddFastEndpoints()
- MapControllers() → MapFastEndpoints()

Next: Migrate existing API controllers to FastEndpoints endpoints
