feat: split admin dashboard, improve match ops, and player closed-match UX

Admin: add match/player overview sub-nav; refine settlement flow and league
match management UI; improve action button enabled/disabled styles; enhance
logo upload and outright odds sync.

API: expose matchPhase/bettingOpen for closed matches; league publish guards;
settlement preview with auto score save; outright team auto-sync.

Player: watermark for closed/settled states; keep match and bet details visible;
remove default login credentials.
