Add config reload support and improve config loading

Introduces a reload_config method to SpotifyClient and refactors ConfigManager to support reloading configuration from a file. Updates web_server.py to use the new config loading mechanism, ensuring configuration is loaded into the existing singleton instance and SpotifyClient is properly re-initialized after settings changes.
