fix: fixes type checking of tuples with primitive types

[aorumbayev]

Adds checks to ensure that type validation applies to classes only.

Changed introduced in 0.5.0 started causing issues for abi methods that return tuple types with primitive types inside.

For instance a method like:

@abimethod(allow_actions=["NoOp"])
    def test_wrapper_get_position_slot(self, user_addr: Bytes, market_slot: UInt64) -> tuple[bool, UInt64]:
        """Temporary wrapper for testing _get_position_slot."""
        return self._get_position_slot(user_addr, market_slot)

Would fail in serialize.py with TypeError: issubclass() arg 1 must be a class. The issue is due to issubclass checks that require first arg to be classes, but when elements inside are primitive types like bool it fails. PR simply tweaks the conditionals to ensure tuples are handled correctly.

I tried reverting the fix and running this test and it still passed, so I think this isn't fully capturing the issue.

Was the issue related to tuples in storage? As support for this was only recently added to Puya. @boblat is currently working on adding support for that to this library

@daniel-makerx The error is unique to versions of python starting from 3.13 and higher python/cpython#101162

Added a ci to run in matrix, here is a run from temporary commit reverting original code back you can see several tests failing due to new behaviour in 3.13 https://github.com/algorandfoundation/algorand-python-testing/actions/runs/15044342246/job/42283130835?pr=39

Nitpick: I think this should be declared closer to the usage or perhaps even inlined as it is used in only one spot.

Should we also add inspect.isclass(typ) clause to the next if statement on line 117 just to be safe?
