v0.10.4 - warm-bed blade measurement

Fixed

• On build sheets that release cold parts (such as BIQU CryoGrip), a calibration block on a bed below 40 °C was not stuck well, and the edge search pushed it back. The block then ended up under the nozzle and the blade was reported as level with the nozzle tip. The measurement now runs on a warm bed (up to 55 °C) right after the block is printed, checks the block's front edge again at the end, and says plainly when the block moved.
