fix: resizing arrow labels (#6789)

* fix arrow labels resizing

- min arrow labels width based on font size
- labels width and padding in % of container's width
- resize labels simply multiplying by scale

* remove no longer needed getContainerDims

* fix arrow labels font size not updated on change font size action

* fix bound arrows not updated right after resize

* fix test

* fix 3+ point arrow label resizing with shift

* fix bound text not scaling when resizing with shift & n or s handle

* fix arrow labels width not updating when moving a 2-point arrow point with shift
