Drops the inner padding on the logo image so it fills the circle right
up to the ring, rather than floating small in the middle of it -- most
visible on logos with generous internal whitespace (e.g. some SVGs).
The control panel's club-detail page now frames the logo the same way.
It doesn't get the page-wide --color-primary override the club's own
site uses (the panel must never dress itself up as the club), so the
ring colour is set as a locally-scoped custom property on just this
element instead.
