No-shows on the desktop member page, coach event screens, "+" popup polish

- management member_detail.html's Attendance card now shows the same
  No-shows count as the mobile player sheet, and the card's content (sparkline
  + tiles) fills the card's height/width instead of sitting in the top-left
  corner -- same flex-1/justify-center + stretched-tiles fix used there.
- Coach mode's Attendance and Line-up screens (opening an event) now
  highlight the Schedule tab instead of Today -- that's the calendar-icon
  tab, and where a coach reaches either from CoachScheduleView's own rows.
- The tab bar's "+" button: rotates 45° into an "×" while its popup is open
  (icon reused via CSS transform, no icon swap needed), the popup sits a
  little higher above the button (mb-3 -> mb-5), and a dark backdrop now
  covers the content behind it so the popup stands out.
