Description of your pull request and other information

Closes #2144.

• Fix: make_dumper's DictDumper.object_hook fallback calls super().object_hook(o) instead of super(type(self), self).object_hook(o), which recursed forever in any subclass.
• Nothing else needed changing: no other super(type(self), …) / super(self.__class__, …) exists in pcapkit/. The three super(<FixedClass>, self) calls (in infoclass.py, fields/numbers.py and schema/misc/pcapng.py) skip a class on purpose, and cannot recurse.
• Tests: tests/dumpkit/test_make_dumper_subclass_2144_unit.py covers JSON, PLIST, Tree, PCAPIO and NotImplementedIO. For each, a subclass, a sub-subclass, and an override calling super() must all fall through. Without the fix, 15 fail with RecursionError. The dumpkit ordering leg gives 298 tests, 0 failures.

GOOD TO GO at 660816df1 (Sonnet review).

• Fix: zero-argument super() is valid in a class body nested in a function, and DictDumper already uses it in __call__, _append_dict, _append_array and _append_number. For the unsubclassed class, the old and new calls resolve to the same next class in the MRO.
• No other recursive sites: no other super(type(self)…) / super(self.__class__…) exists in pcapkit/. The fixed-class super(Info, self) / super(EnumField, self) calls skip a class on purpose.
• Tests: with common.py reverted, the new tests fail 15 subtests with RecursionError, and pass with the fix. The dumpkit ordering leg gives 298 tests, 0 failures.

Ready to merge at 660816df1.

• Review: the Sonnet review is GOOD TO GO.
• CI: every blocking check passed (Required checks passed SUCCESS). The 3.8–3.10 KTLO legs carry no warnings.
• Ordering: the head sits directly on main d7aa41535, and its tests/dumpkit plain-unittest ordering leg ran 298 tests with 0 failures.

This closes #2144.
