test(ignore): document root causes for unannotated #[ignore] tests

74 tests carried a bare #[ignore] with no explanation. Re-ran each:
25 now pass and had the attribute removed; the remaining 49 got a
concise reason (todo!() stubs, regex-crate PCRE gaps, PhpMixed type
mismatches, config bool-coercion bugs, missing skipped_load wiring
in PoolBuilder, etc.) so future work can find and fix them by grep.

No production code or test logic/assertions were changed.
