A meeting invitation puts the join URL in the description - Teams, Meet,
Zoom and the plain iTIP fallbacks all do - and the event detail sheet
rendered it as bare <Text>. The one actionable thing in the event could
not be tapped: you had to select the URL by hand and paste it into a
browser. The mail body already linkifies (plainTextToSafeHtml, rendered
in the WebView); only the calendar was left out.
`splitTextLinks` (lib/linkify-text) splits the text into runs and marks
the http(s) URLs, using the same rule as plainTextToSafeHtml so a message
linkifies identically in the body and in the calendar. DetailRow gains an
opt-in `linkify` prop - set on the description row only, not on rows the
app composed itself - and hands each URL to `openExternalUrl` with
`confirm: true`, the same guard the "Open link" button on the video row
already uses: scheme allow-list plus the host confirmation, since this
text arrives in someone else's data.
