The Busy availability value is the default for nearly every event, so a
"Busy" chip on every detail screen was noise. Show the pill only for Free
(the noteworthy case) and move it to the top-right of the title row instead
of the under-title chip strip. That strip now carries only status/access and
hides entirely when there's nothing noteworthy. Drops the now-unused
event_availability_busy string from both locales.
