fix: change synthetic refiner switch from 0.5 to 0.8 (#2165)

* fix problem

1. In partial redrawing, when refiner is empty, enable use_synthetic_refiner. The default switching timing of 0.5 is too early, which is now modified to SDXL default of 0.8.
2. When using custom steps, the calculation of switching timing is wrong. Now it is modified to calculate "steps x timing" after custom steps are used.

* fix: parse width and height as int when applying metadata (#2452)

fixes an issue with A1111 metadata scheme where width and height are strings after splitting resolution

* fix: do not attempt to remove non-existing image grid file (#2456)

image grid is actually not an image here but a numpy array, as the grid isn't saved by default

* feat: add troubleshooting guide to bug report template again (#2489)
