… modern typing

Fixed add() method to properly handle keyword arguments (year=, month=, day=)
when creating datetime instances. Uses type-safe checks to ensure kwargs are
int before using them for datetime construction.

Test verifies that set() method works properly with keyword arguments only.
Uses modern type annotations with proper return type annotation.

…typing

Implemented validation to raise TypeError when tzinfo is passed as keyword
argument to add() or set() methods, maintaining API compatibility with
original implementation. Uses modern type annotations.

- Queue[T] where T is bound to datetime  < /dev/null |  date
- MockDateTime uses Queue[datetime]
- MockDate uses Queue[date]
- MockTime uses Queue[datetime]
- Removed cast() calls from now(), utcnow(), today(), and MockTime.__new__()
- Uses modern Python 3.11+ syntax with TypeVar bound to union type

- MockedCurrent[T] where T is bound to datetime  < /dev/null |  date
- MockDateTime extends MockedCurrent[datetime]
- MockDate extends MockedCurrent[date]
- MockTime extends MockedCurrent[datetime]
- Updated mock_factory to be generic
- Removed 5 type: ignore comments by improving type annotations
- Improved _correct_mock_type methods with better casting

Note: One test_isinstance_strict test currently failing - needs strict mode fix

Prefer type-ignores instead

The return type annotation in MockedCurrent.__add__ method no longer
needs a type ignore comment as the generic type constraints properly
handle the return value.

Reduced type ignore count from 18 to 17 without introducing any casts
or changing the external API.
