fix(MWPW-190444): remove 512x512 minimum dimension restriction from Firefly upload config

[dstrong23]

Summary

Fixes MWPW-190444 — removes the 512×512 minimum image dimension restriction from Firefly upload flows.

The 512×512 minimum was a product-specified requirement that has since been lifted. The restriction was enforced on the primary upload path but was never applied to the Edit flow (reference image upload from device), causing an inconsistency. Removing the config entries resolves both issues simultaneously: the primary upload no longer blocks small images, and the Edit flow inconsistency is moot.

Root Cause

The 512×512 minimum dimension was hardcoded in target-config.json under limits-firefly as minHeight: 512 and minWidth: 512. This config is merged into this.limits in action-binder.js at construction time and evaluated in checkImageDimensions(). Because isMinLimits is only truthy when both minWidth and minHeight are present, removing these keys from the config causes the minimum-dimension check block to become a no-op with no JS changes required.

The Edit flow (reference image upload via the prompt-bar widget) bypassed uploadImage() entirely and therefore never called checkImageDimensions(), which is why the inconsistency existed. Both paths now behave identically: no minimum dimension is enforced.

Changes

File: unitylibs/core/workflow/workflow-upload/target-config.json

• Removed minHeight: 512 from limits-firefly
• Removed minWidth: 512 from limits-firefly
• All other limits (maxFileSize, allowedFileTypes) are unchanged
• Photoshop and Lightroom limits (limits-photoshop, limits-lightroom) are completely unaffected

No JavaScript changes are required.

Verification

• Confirmed minHeight/minWidth only exist in target-config.json in this repo (no other JS files hardcode these values)
• Confirmed fallback.js reference to minHeight is a CSS property on a browser-compatibility banner — unrelated
• Confirmed no API endpoint dynamically supplies dimension limits — this config is the single source of truth

Testing

• Verify images smaller than 512×512 can be uploaded via the main upload flow on Firefly/Doodlebug pages
• Verify images smaller than 512×512 can be uploaded via the Edit flow (reference image from device)
• Verify images above maxFileSize (100MB) are still correctly rejected on both paths
• Verify allowed file types (JPEG, PNG, WEBP) validation is still enforced
• Verify Photoshop and Lightroom upload validation is unaffected
