Mobile overhaul: round-picker bracket, 5-tab nav + More sheet, real icons

- Bracket on phones: a segmented round picker with full-width cards
  replaces the 1040px sideways scroll; desktop keeps the columns.
- Odds table: sticky team column; the three lowest-value columns hide
  on phones so Team/QF/SF/Final/Champion fit without scrolling.
- Bottom nav: 4 primary tabs + a More sheet (vs Markt, Modell, Story,
  Teams, Daten, plus language & theme toggles) — 7 tabs were cramped.
- Emoji → icons: timeline events use a ball icon, card-shaped color
  chips and substitution arrows; unknown-team fallbacks use a shield.
  Country-flag emojis stay (intentional).
- Readability: bigger scores on match cards, minimum text sizes bumped,
  probability-number triple hides on the narrowest screens (the bar
  carries the information).
