Seems we are good for review now

[KipK]

Mhh not ready to merge, something I've changed crash the fw. Will check tomorrow

Looks good, some great work. Just a few changes and I think this will work well

[KipK]

All changes done, seems we are good to go.
I have to think about the best UX to handle this on GUI now.

I think of a first selector for the Type, then a conditionned input ( time input for time, selector/ or number input for energy, slider for soc, selector/number input for range

@jeremypoulter , I've finished to setup the UI2 for those new limits. Ready to push it when this is merged.
there's a change requested marked but it's outdated i think.

Mid reviewing/testing, hopefully a day or two

I've pushed the gui limit branch here, if you want to test with :

I"ve added new settings in the /config , it allows to set a permanent limit. On the UI side I'll place it in the configuration section, to differentiate from limits from the main charging page.
Limits from the main page has auto_release = true, and can be deleted from the main page.
Those from the config, with auto_release = false have a lock icon instead of a delete one when displayed on the home.
They can only be deleted from the config. I haven't made the config part on UI yet
