test: remove outdated tests and stabilize ordering

The queue tests skipped on macOS arm64 were hiding nondeterministic behavior
when multiple entries had the same priority. The priority queue now keeps
insertion order for equal-priority items, which makes the execution order
stable across platforms and allows those tests to run normally again. A
regression test was added to cover this case.

The resolve tests were also carrying three skipped cases that expected
v1beta1 conversion failures from fixtures that are now accepted by the
current parsing path. Those outdated skips were replaced with assertions
that verify the fixtures are parsed successfully and produce no validation
errors.

Together, these updates remove unnecessary skips, improve determinism in the
queue package, and align the resolve test suite with current behavior.
