* ✨ Implement optional API token in config-flow + options
to make the data download from an authenticated path in ESIOS server
As this is an *alternative* access, and current public path works for the PVPC,
no user (current or new) is compelled to obtain a token,
and it can be enabled anytime in options, or doing the setup again
When enabling the token, it is verified (or "invalid_auth" error),
and a 'reauth' flow is implemented, which can change or disable the token if
it starts failing.
The 1st step of config/options flow adds a bool to enable this private access,
- if unchecked (default), entry is set for public access (like before)
- if checked, a 2nd step opens to input the token, with instructions
of how to get one (with a direct link to create a 'request email').
If the token is valid, the entry is set for authenticated access
The 'reauth' flow shows the boolean flag so the user could disable a bad token
by unchecking the boolean flag 'use_api_token'
* ♻️ Remove storage of flag 'use_api_token' in config entry
leaving it only to enable/disable the optional token in the config-flow
* ♻️ Adjust async_update_options
* ✨ Add new price sensors with API token access
New price sensors added:
- Injection price: price of excess energy from self-consumption
- OMIE price: electricity price in the 'open' market
- MAG price: Temporal tax cost for gas compensation
* ✅ Adapt tests to work with multiple sensors
* 🐛 Fix all integration sensors going unavailable
when any sensor lacks data for the current day (usually the 'OMIE price')
* Fix rebase
* Customize icons and display precision for new sensors
* Disable MAG Tax and OMIE price sensors by default
* Move logic to assign sensor unique ids to integration
* Move helper functions to helpers.py
* Fix sensor activation for API download
