style: letter avatars for members, drop row hover, round partner rows

Use letter-initial avatars in the Members table (matching pending
invites) and drop the unused photo/UserAvatar path. Remove the hover
highlight on member and pending-invite rows. Give partner-node rows a
4px radius by painting the hover/selected background on the cells with
rounded end caps (table rows can't render border-radius directly).
