Remove leftover key tile on the crate; damage keeps the player in place

The key object moved next to the spawn, so the key tile painted at cell (10,8) (on top of the crate tile) was left behind and rendered a second key. Cleared it by setting that record's source_id to -1, which is a same-length edit inside the base64 tile_map_data. Also hurt() no longer teleports to the spawn point, it only drains a heart and grants brief i-frames; only dying returns the player to the spawn.
