feat: add region checks and site coverage

region_check.py runs each region game of content.yml with every regional BIOS, its own only, the others only, and the region-filtered pack, and reads the outcome from the records: the file opened settles region:, the verdicts say whether the BIOS is locked. System pages show the outcome with its records, the Measurements page lists which systems are tested and why the others are not. The campaign text says a maintainer starts each pass.
