Add game selection screen and new run wizard

Build a 3-step wizard at /runs/new: select game (themed gradient cards
grouped by generation with filter tabs), configure rules (reuses existing
RulesConfiguration), and name/create run. Remove standalone Games and Rules
pages since they're now integrated into the wizard flow.
