fix: catch ConfigError in display preview generator

Browse Source 
PR #282 narrowed bare except blocks but missed ConfigError from
config_manager.load_config(), which wraps FileNotFoundError,
JSONDecodeError, and OSError. Without this, a corrupt or missing
config crashes the display preview SSE endpoint instead of falling
back to 128x64 defaults.
