some CSS upgrades: move to dart sass 3 compatible, logical CSS properties for rtl

[MosheL]

1. Move to SASS 3 compatible:
   1. Remove the darken() and ligten())
   2. Move from scss import( to use().
2. Move from left/right to logical CSS properties (this for better compatibility with RTL without duplicates).
3. Upgrade to Vue 3.5
4. move to rollup 4 and its friends, support for new versions of things.

for now I do not removed the "rtl" and -left, -right from Table.vue, as my version has some other modifications I need to prepare to pull request.

just to note: I was upgraded rollup and friends to support the new SASS and vue plugins.
