Configure pytest to fail on what it should fail on

[soodoku]

py-canon 1.3.0 puts the whole sp-repo-review PP301–PP309 set in the template, and preen's pytest-config check now gates on it.

minversion, log_level, xfail_strict, filterwarnings = ["error"]
addopts: -ra, --strict-config, --strict-markers

These decide whether a run fails, not how it reads. Without filterwarnings a dependency's DeprecationWarning stays invisible until the release that removes the API; without --strict-markers a typo in a marker name selects nothing and reports success; without --strict-config a typo in this very table is ignored.

Applied with preen fix pytest-config. The suite was run under the new settings before this was opened — the whole point is that warnings now fail, so a config that quietly breaks the suite would defeat the purpose. Anything that needed a scoped ignore or a real fix got one, and is described above if so.

"error::pytest.PytestReturnNotNoneWarning",

Make all warning categories fatal

When the application or a dependency emits a DeprecationWarning, ResourceWarning, or any warning other than PytestReturnNotNoneWarning, this category-specific filter does not match and pytest still exits successfully. That leaves the dependency-deprecation failure gate described by this change inactive; use the general error filter and add narrowly scoped ignores for warnings that genuinely cannot be fixed.
