Implemented tabbed game page (Game/Lineups/Stats) with manager-aware default tab logic. Key fixes: 1) Per-team lineup submission allowing independent team submissions, 2) Lineup persistence via lineup-status endpoint that queries database directly for pending games (avoids GameState validation error when inning/half are null), 3) LineupBuilder populates from saved data after rosters load. Pattern: For pending games, query DB directly instead of trying to recover full GameState.
