Server overhaul: invite creation and CLI plumbing shared

invites::create_partner_invite is the one partner-invite path of E-12 and invite-partner; E-3's user creation moves
into invited_user; invite kinds parse through rows::token; app_version_code comes from auth. cli::render_invite
replaces the two identical render functions and cli::with_database the open/run/close block of four subcommands.
Same output, exit codes and errors.
