refactor(theme-studio): dedup the inline-integrity test scaffolding

Two test-DRY cleanups. The seven near-identical test_page_carries_*_verbatim
methods in test_generate.py collapse into one subTest loop over the inlined-body
names. The strip-exports helper -- reimplemented three times across the colormath,
app-core, and app-util inline-integrity tests, each annotated 'same strip
generate.py applies' -- moves to one shared inline-strip.mjs (stripInlinedBody),
so the three copies can no longer drift from generate.py's strip_exports.
