fix(serde): resolve generic-dataclass type parameters on Python 3.12

Decoding a PEP 695 generic dataclass (e.g. `Box[int]`, declared `class Box[T]`)
raised `CodecError: name 'T' is not defined` on Python 3.12. The field
annotations reference the class type parameters, and 3.12's `get_type_hints`
does not place those parameters in scope (3.13+ resolves them automatically).

Pass the class `__type_params__` through `get_type_hints`'s `localns` so the
annotations resolve on every supported interpreter. Verified against the full
suite on 3.12, 3.13, and 3.14.
