Splits provisioning (softAP + captive portal + NVS-backed config) into wifi_provisioning.c and home-network connection into frame_client.c. /save_config now parses the form body and persists it to NVS; on boot the device goes straight to STA mode if a config exists, retrying a few times before falling back to provisioning if the home network is unreachable. The provisioning AP is now always named ESPRESSO with a random per-device password (generated once, persisted in NVS) instead of a fixed Kconfig value, drawn from a charset that avoids visually ambiguous characters since it'll be read off the e-ink panel and possibly typed by hand.
