@diosmosis working as expected, test VUE parts, interface, and CSS. I did conflicts resolve for this PR. Can you review it, in case I merge the wrong parts?
@peterhashair I'll check eventually, but these PRs are all based on each other like a chain. The next one to review is https://github.com/matomo-org/matomo/pull/18430, then when that gets merged I'll merge into the next PR, etc. This PR, eg, contains changes in other PRs so I wouldn't want to get this merged right away, instead would look at the PR it's based on first.
This is the link I've been using to look at the PRs in the order that they were created: https://github.com/matomo-org/matomo/pulls?q=is%3Apr+%5BVue%5D+sort%3Acreated-asc+is%3Aopen
@diosmosis this seems to work fine. While testing I discovered anther bug in RollUpReporting that seems to be caused by the vue migration (at least it worked with Matomo 4.5).
Feel free to merge this one and create another PR for that if you find a fix.
