exceptions: call super().__init__() in APIError

[prashantbytesyntax]

Summary

APIError.__init__ never calls super().__init__(), so the base Exception machinery is left uninitialized — most importantly self.args, which breaks repr(e), pickling, and any code that inspects e.args (including some logging configurations and multiprocessing propagation).

This PR:

• Forwards message to super().__init__(message) so the standard Exception state is populated.
• Tightens the full_data parameter annotation from dict = None to Optional[Dict[str, Any]] so it actually matches the default value and what the call sites pass (a parsed JSON response dict, see gprofiler/client.py).

No behavior change for the existing call sites in client.py — str(e) still returns self.message, and e.full_data is unchanged. The only observable difference is that e.args is now populated and repr(e) works as expected.

Before / after

>>> e = APIError("boom")
# before: repr(e) == 'APIError()'  and e.args == ()
# after:  repr(e) == \"APIError('boom')\"  and e.args == ('boom',)

Test plan

• Existing tests pass (./tests/test.sh)
• ./lint.sh is clean
• Manual sanity: construct APIError("msg") / APIError("msg", {"k": 1}) and confirm str(e), repr(e), and e.full_data behave as expected
