UI - Consolidate BTR UI with other Nuxt projects

- import common components from existing repos into their own repository so we can use them without copying and pasting and import them as layers instead
- pull btr-common and btr-layouts outside of btr-web so that it only contains btr-main
- *NOTE*: business-dash has most recent header/footer (small tweak differences) + common stores (no axios and small bug fix with account switching)
- consolidate colour themes across btr-web / bor-ui / business-dash (they are slightly different)
- update app.config so that the common one can be applied to all 3 projects without conflicts
- *update btr-web to apply different styles primarily based on colour instead of variants where possible*
- update style for BcrosTooltip in the app config to stops truncating text
- css that helped: `class="whitespace-normal place-content: center"` see if it can be added to app.config under toolitp `base `style

Spoke with thor on this a little bit and the AR team is planning on making common nuxt repos ahead of us. We are thinking BTR will use the business-dashboard-ui as our base layer / consolidate it within the BTR projects (btr-main, director search, business-dash) and then consolidating that with the common layers they are building aferwards. I will be in contact on their team to try and make sure most of our base layer stuff getting built is similar
**suggestion**: turn this into an epic with a story for BTR consolidation and another story for cross team consolidation (this one would likely be started post mvp or near release when most things are done changing)
