The on-chain wallet rewrite (3a703a26) replaced the single
`esploraBaseUrl` config field with an ordered `esploraApis` array
that `verifyOnchainZap` failovers across, but `ProfileCampaignsTab`
and `useProfileCampaignStats` still pulled the old name off
`AppConfig` and passed a string where the array is now required —
the two surviving call sites from the original Esplora API.
Switch both to destructure `esploraApis` and pass it through to
`verifyOnchainZap` to match the new signature.
