Optional weather source fields used the current selection as the form
default. A cleared field that the frontend omits was refilled with the
old sources by voluptuous, and an options key missing from the
submission fell back to the original setup data. Optional providers
could therefore not be removed in the UI.
Pre-fill with suggested values instead, and save omitted optional lists
as empty so they override older entry data. No UI strings changed.
