Works out a part's inputs from its mappings, in the plan's order: the dashboard property's value
(host, then event, then the property's default, already in values), then the mapping's default,
then the input's own default (no key: the part applies it).
A required input with none of these is missing. An unmapped input the user fills on the part (a
query parameter) is left to the user; one only the server sets is never missing here.
