refactor: restructure game menu with two-row tab layout

- Split category tabs into two rows: row 1 (tabletop, cards, casino, word),
  row 2 (logic) for better screen real estate
- Move title text and adjust vertical positioning to accommodate tabs
- Center row 2 tabs independently based on active categories
- Update game grid top position to 370px for proper spacing
- Update game-icons and tab-icons assets for new layout
