fix(client): test harness tile types, bug report screenshot, time_display maxf

TestHarness: remove deprecated tiles/visible_positions keys, add tile
type (floor/wall/door) to visible_tiles, expand radius to 5. Bug report
dialog: capture viewport screenshot before showing overlay, save as
screenshot.png in report bundle. time_display: use maxf() instead of
max() to match float argument types.
