- Replace timestamp comparison (help_last_viewed vs a hardcoded date) with
a content-version marker (data-help-content-version) read from the
rendered modal markup, so badge state always reflects the content
actually served
- Only mark content as viewed when the modal is opened while it contains
new content; opening a stale pre-upgrade page no longer suppresses the
badge after a refresh
- Flag the Replay Tutorial button itself with a 'New' chip (hidden by
default, one-time glow animation) and scroll it into view when
revealed; tab-level dots now mark getting-started and shortcuts
instead of documentation
- Translate help.newContentBadge into all 9 locales, reusing the
established help.documentation.newBadge renderings
- Add HelpManager content-version unit tests (12 cases)
