"""Static-contract regression tests for the composer footer-control visibility
toggles (#4598).

Mirrors the sibling pattern in test_sidebar_tab_visibility.py: pins that each
toggle is wired end-to-end (config boolean key -> boot.js definition + read-back
-> index.html control -> panels.js chip render -> apply) and that every new i18n
key exists across all locale blocks, so a future refactor can't silently orphan
a control or break locale parity.
