fix(vdd): remove vdd_display_configs from config system and revert unrelated changes

Remove vdd_display_configs from config.cpp registration since it is
auto-managed by VDD persistence, not user-configurable. Read configs
directly from the config file in main.cpp instead. Revert i18n label
lookup in config.html (unrelated to VDD feature) and non-default
locale changes (should go through Crowdin).
