docs(dom_widget_dev_guide): clarify dynamic resizing and add performance note

- Add performance note explaining that providing `getMinHeight` and `getHeight` via `options` avoids expensive DOM measurements
- Expand dynamic resizing section with detailed update sequence and common scenarios table
- Update LoraPoolSummaryView.vue with `min-height: 0` to allow flex shrinking
- Update main.ts to provide `getMinHeight` via options and adjust `computeLayoutSize` for performance
