Add a home-location box to the club detail page in the control panel

Setting a club's home ground here creates/updates the same events.Location
row (flagged is_home) that the club's own Teams > Locations page shows and
edits -- no separate sync step, it's the same record either way. Also
fixes the shared form_field templatetag: django-countries' CountryField
widget reports as "lazyselect", which fell through to a broken plain
text input instead of rendering as a dropdown.
