docs: point remaining src/ui.js references at their owners

The README source tree now lists src/ui/ instead of the removed
src/ui.js. docs/CODE-BOUNDARIES.md names src/ui/applicationShell.js as
the owner of panel layout, persistence and share restoration, and
docs/CURRENT-STATE.md places GLOBAL_POST_DEFAULTS in
src/ui/visualPresets.js. QA script comments and test assertion messages
that still named ui.js are updated the same way.
