Questions about list_crowdloans
Fetch every crowdloan the chain currently holds a record for (#8696, part of the subnet-leasing/crowdloan-tracking epic #6717), decoded from the Crowdloan pallet's storage at request time (not a rollup). Each record carries creator, deposit_tao, min_contribution_tao, cap_tao, raised_tao, end, funds_account, contributors_count, finalized and percent_raised. crowdloan_count can be LOWER than next_crowdloan_id: dissolve removes a record while NextCrowdloanId keeps counting, so ids are not dense -- iterate crowdloans, do not count up to next_crowdloan_id. percent_raised is null when cap_tao is 0 (representable on-chain, and dividing by it is not). has_dispatch_call is presence only: decoding the Option<Bounded<Call>> payload needs the full runtime type registry, which a Worker does not carry.
