edit_authelia_user() previously only ever let you select one user, act on
them, and then returned all the way out of install_authelia() (which calls
it with an immediate `return 0`) — deleting several users meant re-running
`sudo ./setup.sh authelia` and re-navigating to option 3 from scratch for
every single one.
Restructured: the per-user action menu (edit/reset-password/2FA/admin/
service-access/delete) is now _authelia_manage_one_user(), and
edit_authelia_user() drives it in a loop — numbered multi-select up front
("2 4" deletes/edits both), then "Manage more users?" to go again with a
freshly re-read user list instead of exiting. Guards against acting on a
user who was already deleted earlier in the same batch.
Verified against a synthetic users.yml: selecting two users by number and
deleting both in one pass removes exactly those two, leaves the others
untouched.
