The privacy instructions no longer bloat the launcher card.
A "Help" button in the navbar opens them in a native dialog
(Esc, backdrop and button close it). The button only shows
for Windows users, reusing the existing OS detection.
Translations may contain <kbd>, <b> and <i> markup now. The
renderer builds nodes from a tag whitelist instead of using
innerHTML, so smuggled tags from i18n.json cannot execute.
All help texts live under meetingPrivacySettings.windows;
sibling keys for other operating systems can follow.
