bug: Method parameter injection fails for hyphenated request param names

[usernane]

Problem Statement

When using #[ResponseBody] with method parameter injection, the framework resolves parameters by the PHP variable name, not the registered request parameter name. This breaks for any hyphenated parameter name (which is the standard convention in WebFiori).

Steps to Reproduce

#[RestController('my-service')]
class MyService extends WebService {

    #[GetMapping]
    #[ResponseBody]
    #[AllowAnonymous]
    #[RequestParam(name: 'app-id', type: ParamType::INT)]
    public function myMethod(int $appId): Json {
        // $appId is always null
        return new Json(['id' => $appId]);
    }
}

Calling with ?app-id=5 results in $appId being null (or a TypeError if not nullable).

Root Cause

In WebService::getMethodParameters():

foreach ($reflection->getParameters() as $param) {
    $paramName = $param->getName(); // returns 'appId' (PHP variable name)
    $value = $this->getParamVal($paramName); // looks for 'appId', but param is registered as 'app-id'
    $params[] = $value;
}

The PHP variable name appId doesn't match the registered request parameter name app-id, so getParamVal() returns null.

Expected Behavior

The framework should convert the camelCase PHP variable name to the hyphenated form (e.g., appId → app-id) before calling getParamVal(), or try both forms. This is consistent with how WebFiori uses hyphens as the convention for parameter and column names throughout.

Workaround

Access hyphenated params manually inside the method body:

public function myMethod(string $username): Json {
    $appId = $this->getParamVal('app-id'); // works
    // ...
}

Only non-hyphenated params (like username) can be injected as method parameters.
