Introduces a settings reset subcommand with choices so admins can clear one guild override at a time via MongoDB $unset, with live player sync for volume and duplicate-track defaults. Adds settings.actions.resetDone across language files and optional reset aliases (restore, defaults) in settings examples.
Improved docstrings for 'play' and 'search' commands in basic.py for clarity. Updated localization keys and translations in es-419.json, es-ES.json, and zh-CN.json to fix punctuation, naming consistency, and minor translation errors.
