fix(profiles): name the Plex user and account in one translated chip

A Plex account connection labels itself with the account owner's name.
Under a profile tile that reads as being signed in as the owner: the
Plex Home tile showed the owner beneath the Home user's own name, and a
local profile that borrowed a Home user out of someone else's account
showed only the lender.

Both halves of the relation now go through a single translated string,
so a locale orders them itself instead of inheriting the English
"user via account" — az, hu, ja, kk, ko, tr, uz, zh and zh-Hant put the
account first. When the Home cache cannot resolve the connection's uuid
the chip names the account alone rather than falling back to a bare
name. ProfilesView carries the Home user cache that resolution needs,
and chip labels ellipsize now that an account label can be an email.
