Let Edit Source account actions be rows focus can reach on tvOS

The account rows hung everything off a contextMenu, which tvOS can
only open on a focused element — and a bare Form row is not one, so
focus skipped from Password to Add Account and the actions were
unreachable (TV2). The Accounts screen already solved this by
emitting the actions as sibling rows on tvOS; the section now shares
that shape, keeping the context menu everywhere else.
