Fix and check builders: every fix is built from fields; today's 27 fixes carry their templates

settings/builders.py renders a fix's command from a builder (template) and its fields; validate
refuses a config whose stored command no longer equals what its fields build; the Fixes screen and
the remote checks in the key editor rebuild through /api/build and /api/build-check. config.json
adopts templates for all 27 fixes and 5 remote checks (ProPresenter's restart loop and Ableton's
quoting normalised, same behaviour); tests/test_builders.py (174 tests pass). Deployed to NA Ingest.
