Board submenu now registers at admin_menu priority 11 (parent toplevel at 10)
so the page hook lands under prautoblogger_page_prautoblogger-board; $submenu
reordered defensively to keep Board the first item / top-level click target.
Enqueue gate now matches; board.css/board.js load for the first time on prod.
Regression test: BoardMenuRegistrationTest (fails on pre-fix main).
