fix: handle invalid images in deepfry

[vycdev2]

Summary

• Prevent the deepfry command from failing on malformed or unsupported image bytes.
• Catch image inspection/processing errors and return a user-facing retry message instead of letting the command handler fail.
• Add a regression test for invalid image data.

Verification

• dotnet test --no-restore --filter FullyQualifiedName~ImageModuleTests --logger "console;verbosity=minimal" — passed (1/1).
• dotnet build --no-restore — passed (0 errors; existing SDK/package warnings).
• dotnet test --no-build --logger "console;verbosity=minimal" — 298 passed, 2 failed in existing MiscModuleTests because this runner uses globalization-invariant mode and cannot load tr-TR.
• git diff --check upstream/develop...HEAD — passed.
• dotnet format Morpheus.sln --verify-no-changes --no-restore — failed on pre-existing repository-wide formatting violations outside this change.

Risk

• Low: only changes error handling for the deepfry command; valid image processing remains unchanged.
