fix+test v1.13.2: audit round 3

- 12-test buildDevices suite on a fake hass (curation, markers, groups, dedup,
  icon rules, lock override, device_class fallback, primary/LQI/temp)
- t() substitutes all placeholder occurrences (pure subst() + regression test)
- _saveConfigNow resyncs config on rev conflict before rethrowing
- pointercancel clears the long-press timer (phantom info card on touch)
- repairs.py: plan-file check re-runs after every config save
- test build compiles devices.ts/types.ts; fix-test-build.mjs adds .js to ESM imports
