🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject invalid heading levels before the sequence check.

In tests/e2e/admin-screen-headings.spec.ts, Line 31, Number() accepts zero, negative, and fractional values. A sequence such as [1, 0] or [1, 1.5] passes Line 38. The test can therefore pass invalid heading markup. Assert that every level is a positive integer before the loop. Add an edge-case check for invalid aria-level values.

As per coding guidelines, verify all external and variable inputs before use and cover edge cases for new logic.

In `@tests/e2e/admin-screen-headings.spec.ts` at line 31, Validate the heading
levels produced by the map in the admin heading test before running the sequence
check: require every level to be a positive integer, rejecting zero, negative,
and fractional aria-level or tag-derived values. Add an edge-case assertion
covering invalid aria-level input while preserving the existing valid heading
sequence behavior.
