Reverts
- DEV: maxmind license checking failing tests #24534
- UX: Show if MaxMind key is missing on IP lookup #18993
These changes are leading to surprising results, our logs are now filling up with warnings on dev environments
We need the change to be redone
1. Use `this.` instead of `{{action}}` where applicable
2. Use `{{fn}}` instead of `@actionParam` where applicable
3. Use non-`@` versions of class/type/tabindex/aria-controls/aria-expanded
4. Remove `btn` class (it's added automatically to all DButtons)
5. Remove `type="button"` (it's the default)
6. Use `concat-class` helper
