METHOD_ADD and ADD_METHOD_TO do not consider unsigned types

[Mis1eader-dev]

Describe the bug
Creating an HttpController with methods that take in uint64_t for example, and making a request to -1 will underflow and become UINT64_MAX.
Another related bug is if the URL contains characters, it still processes it.

Expected behavior
Should give 400 Bad Request upon error.

Desktop (please complete the following information):

• OS: Ubuntu

Additional context
For the time being the only choice is to take by string and do validation manually.

In case this issue gets tackled, there is std::from_chars for ASCII to primitive number type conversion, which resides in the <charconv> header.

A proper checker would look like this:

string_view param = "123d";
uint64_t num;
if(std::from_chars(param.begin(), param.end(), num).ptr != param.end())
    return error;

// success, do something with [num]
