ci(crewing): match the whole stack with a feat/crewing-* glob

Replace the per-branch PR-checks trigger ([master, feat/crewing-foundations])
with [master, "feat/crewing-*"] so every branch in the stacked crewing series
(foundations → requisitions → candidates → …) runs the same hard gates without
adding each one by hand. The workflow is evaluated from the branch under test,
so the glob is propagated down the stack.
