Resolve CE-1924 "Tab warnings"

What this does:

• replaces conditional showing of tabs with a custom component that does this without warnings
• fixes warnings that became visible / obvious once the above was fixed
  • Autocomplete prop type issues (e.g. expected a Boolean but got an object, undefined, etc)
  • impure render in LokiPanel (was making state changes during render / outside an effect)

What to look for:

• Are the warnings silenced?
• Are there other warnings I missed?
