fix: scope --accepted to the same page; record current counts (GSTA-92)

The craft section passed --accepted whenever a finalized.json sat beside
the page, so a same-day Start fresh build inherited the old page's
exceptions. It now passes them only when evolving or rerunning a page it
finalized, records the count the check reports now, and writes [] when
nothing was accepted instead of the template's placeholder entry. A test
pins exit 2 for a clean page with a broken exceptions file.
