static/ui.js provides promise-based rgConfirm/rgAlert that show a themed
modal matching the app, injected self-contained so it works on any page
including the standalone client. Every native alert()/confirm() is
replaced: delete user and revoke token (admin), revoke token (tokens),
delete recording (recordings), popup-blocked (client), and terminate
session, delete entry, delete folder and the SSH host-key probe
(connections). Destructive actions get a red confirm button, the host-key
trust prompt an accent one.
From an independent review of the module: rgConfirm/rgAlert resolve any
already-open dialog before replacing it, so a second call can't leave the
first promise hanging; Enter acts on the focused button (Cancel cancels),
and Tab is trapped between the two buttons.
