* refactor(community_tokens): only fetch holders when going to the page
Fixes#16307
Instead of fetching community token holders each time members change, we fetch when the page for the token is opened.
It shows a small loading text then the resulting holders.
If the list is already available (fetched previously, we show it directly).
There is still the timer to refresh the list if you stay on the page.
* add loading property to storybook
