Fix custom resolution validation rejecting valid multiples of 32

修复自定义分辨率 bug（Fix custom resolution validation）

Problem

geometry() and the latent upscaler validated dimensions with strict Python-native integer checks (isinstance(n, int) / type(n) is not int). When width/height were provided as a string from a typed widget ("640"), a numpy integer (numpy.int64), or an integer-valued float, they were wrongly rejected with:

Width and height must be multiples of 32, at least 256 pixels.

This happened even when the value was a perfectly valid multiple of 32 (e.g. 640x960). The built-in presets worked because they submit a native int, while manually entered custom values arrive as strings.

Fix

• Normalize each dimension with float() and compare by numeric value before validating the >= 256 and % 32 constraints.
• Apply the same normalization to the latent upscaler's target-size check (used in the second pass).
• Non-numeric, fractional, undersized, and non-multiple-of-32 values are still correctly rejected.

Tested

Using the main environment Python, with 640x960:

• 640, "640", 640.0, numpy.int64(640) → all accepted
• 642 (not multiple), 128 (too small), "abc", "640.5" → all rejected
