UI/UX pass: i18n completion, responsive fixes, cleanup

- Fix flex 'align=flex-start' shrinking content to min width in column
  mode on matches, dashboard, and coupon-builder layouts (mobile/tablet
  cards now span full width)
- Localize all user-facing hardcoded Turkish strings: lineups card,
  odds card, v28 odds band panel, team/league pages, teams search,
  auth toasts, league headers (new keys in tr/en messages)
- Populate empty predictions.prediction-reasons group (20 veto reasons)
  and missing predictions.ui keys so the EN locale gets full coverage
- Use the active locale for all date formatting instead of hardcoded
  tr-TR (match card, match detail, team detail)
- Replace raw native date input with Chakra Input (dark mode + theming)
- Rename match-detail first tab from 'Tüm Maçlar' to 'Genel Bakış'
- Fix '4 maçlar' grammar with a proper {count} maç message
- Delete dead 3300-line Chakra showcase component (home-card.tsx)
