refactor: migrate routes to tiered host-based structure (#185)

* refactor: migrate routes to tiered host-based structure

Refactored the HTTP routing layer to support distinct public and admin
interfaces based on request hostnames, while introducing a embedded SPA
serving capability.

- Moved handlers and middlewares to `internal/http` subpackages.
- Introduced `RequireHost` and `RequireProxyAuth` middlewares.
- Added support for static asset hosting via `embed.FS`.
- Separated public DNS/mobileconfig traffic from protected admin routes.

```mermaid
graph TD
    Request[Incoming Request] --> Router{Match Host?}
    Router -- Public Host --> PublicGroup[Public Endpoints]
    Router -- Admin Host --> AdminGroup[Admin Endpoints]

    PublicGroup --> DoH[DoH Handler]
    PublicGroup --> Config[MobileConfig]

    AdminGroup --> Auth[Proxy Auth]
    Auth --> API[Admin API /api/*]
    Auth --> SPA[Embedded UI]
```

* test: update integration test host and clean test file

- Updated `AllowedHosts` in integration tests to use `127.0.0.1` for
  better local test environment compatibility.
- Removed legacy ACME challenge endpoint test case from `test.http` as
  it is handled by internal TLS logic.

* refactor: improve error handling and routing logic

- Refactor `RequireBasicAuth` to return an error instead of panicking on
  invalid configuration.
- Update metrics endpoint registration to use the updated middleware
  pattern.
- Add an explicit 404 response for undefined API paths within the
  `AdminGroup` route handler.
- Clean up debug print statements in the router logic.
