fix: show fallback_model as commented-out YAML example in config

Browse source 
Remove fallback_model from DEFAULT_CONFIG (empty strings were useless
noise). Instead, save_config() appends a commented-out section at the
bottom of config.yaml showing the available providers and example usage.

When the user actually configures fallback_model, it appears as normal
YAML and the comment block is omitted.
