Bring back two-layer configuration: build-time defaults from mimi_secrets.h with runtime NVS overrides via serial CLI. NVS values take highest priority so a pre-flashed board can be reconfigured anywhere with just a USB cable. Restored CLI commands: wifi_set, set_tg_token, set_api_key, set_model, set_proxy, clear_proxy, set_search_key. Added new commands: config_show (displays all config with sensitive fields masked), config_reset (clears all NVS overrides), and help (lists all commands).
