not sure if i missed them in the other patches, but i think
we should wrap these natural language error messages with tr!() so that
we can translate them

as mentioned off-list, i think it would be good to show an explanation,
in case the grid is empty. something like: no remotes with
evpn controllers found or something similar

nit: we actually currently trying to avoid thread_local, since
it's most often not worth it. (upfront cost, vs on component load)

i'd just do the same as in the other componens with having
a 'column()' method and call that on creation
