fix: reservation card header overlap on mobile (#810)

Status and category chips collided with the reservation title on
narrow viewports because the header was a single-line flex with
inline chips of natural width. flexWrap on the outer row plus the
inner chip group lets the title+actions drop to a second row when
content overflows, so the chips and the title never overlap.
