fix(ui): name the popover copy buttons after the field they copy

The shared user popover copied alias, email and ID through three copy
buttons that all announced themselves as "Copy ID", so a screen reader
could not tell them apart. IdCell now takes the label, defaulting to the
old text everywhere else.

Also drops the closest("tr") the new link tests used, which put the
testing-library/no-node-access budget over its ceiling, and asserts the
sentinel row leaves User Email and the admin badge unlinked too.
