1.0.0+kodimov.4: password-less first login from the Movistar network

On a new box the home-network login now also finds the account number
(accountInfo) and registers the box as a device, so no email, password
or account number is needed. The new device id is saved straight away,
so a retry reuses it instead of adding another one. Error pages from the
new servers (including HTML 401s) are retried.

Tested live on 2026-11-07 with a fresh profile; the test devices were
deleted afterwards.

 What it adds:
-- **Login from the Movistar home network**, no password. The home-network login gives a token for Movistar's new servers, which is traded once for a classic token; the classic servers renew it every 10 days. It needs the account number (taken from an existing login, or set in the settings) and an already registered device.
+- **Login from the Movistar home network**, no email, password or account number. On first open, on a box connected to the Movistar home network, KodiMov+ gets a home-network token, finds the account, registers the box as one device (like a password login does) and trades the token for a classic login, which the classic servers renew every 10 days. Outside the Movistar network, log in once with the email and password (Accounts > Cuenta 1 > Login with username).
 - **Takes over the login of plugin.video.movistarplus** on first run (same registered device, so no new device is added to the account).
 - **Hides channels it can't play**: Movistar marks football and premium sports with `QMWatermark`; LALIGA and Liga de Campeones refuse their manifest, while M+ Deportes, DAZN and DAZN Baloncesto play and are kept (`resources/lib/kodimov.py`).
 - **Extra free channels** in the TV guide list: TVG2 (10) and TeleVigo (15).
