BUG: File write errors ignored in debug logger

[andrinoff]

Describe the bug
Debug logger at view/html.go:256-261 ignores file write and close errors. Uses pattern _, _ = f.WriteString(msg) and _ = f.Close() which silently fails.

To reproduce

1. Set DEBUG_IMAGE_PROTOCOL_LOG env var
2. Fill disk or remove write permissions
3. Debug output silently lost

Expected behavior
Log errors or use defer with error check

Matcha version
