minor templates refactor

[codeofcarbon]

refactor mainly touches expanded tags, which I removed where those weren't needed, pl[us some other minor stuff like gathering colors in one place. No features improvements here 😺

Yepp - better!
Thanks for adding all those semicolons after the const lambdas - funny, that I seem to keep forgetting those :-/
Actually, this finding showed me, that we don't use the linter yet... otherwise it would have told ...

Hmm - did you see in discord-server:
Linting throws errors for v-text / v-html use in components:
The rule is: https://eslint.vuejs.org/rules/no-v-text-v-html-on-component
And here is some (convincing IMO) discussion, why it makes sense: vuejs/eslint-plugin-vue#1724

So I guess we should not use v-text and v-html... But I would not mind merging this anyway.. What do you think?
