Give outline buttons an explicit neutral color

Every plain btn-outline (Cancel, Edit, Search, Waive payment, ...) rode
on daisyUI's default outline color, which reads as primary-tinted in
some themes -- explicit btn-neutral keeps secondary actions visually
distinct from the real primary/error actions beside them.

Also gives the club edit form's fields an explicit layout (a spacer
next to the logo upload, season settings paired with branding) instead
of a generic field loop.
