Support Hidden Wi-Fi Networks and Complex Passwords (Spaces & Special Characters)

Description
When configuring Wi-Fi from the terminal on Carvera Firmware v1.03, it is not possible to:
	1.	Connect to a hidden network via the CLI (no --ssid or --hidden flag support for manually specifying SSID).
	2.	Supply a password containing spaces and/or special characters through the CLI (e.g. "My Pass#123!" is rejected or truncated).
