Library grid browsing improvements

Pages that are already indexed now become interactive instantly, instead of waiting for a redundant per-tile readiness pass.
Tile selection within a page now uses a lighter incremental redraw (only the previously and currently selected tiles plus the title line are updated) instead of repainting the entire grid, making navigation feel smoother.
Cover generation, indexing, and library refresh logic are unchanged.
