refactor(measure): centralize measure type config and migrate API

- Add unified MEASURE_TYPES config in types/measure.ts
- Export MEASURE_MODES_ORDERED, ENGINE_TYPE_TO_MODE, MODE_TO_ENGINE_TYPE
- Refactor measure-dialog-manager to use centralized config
- Refactor measure-panel to use MEASURE_TYPES for icons/order/valueType
- Simplify engine/index.ts measureMap with dynamic key access
- Add measure settings API (saveMeasureSetting) with cache sync
- Add direct engine event listening for measure-changed and section-move
- Update i18n keys for 8 measure modes
