refactor(frontend): CSS pay-down, derive batch (milestone 302 step 4) — page-header, error-msg/state-msg/empty-msg, empty-title/empty-sub, required, field-hint recipes into components.css; form-buttons into rules-shared.css; scoped copies trimmed to remainders/overrides; the three views' .input becomes fs-input + width/box-sizing remainder (canon #2336)
