test_rln_proof_attach.nim (added in #4069) postdates this branch, so its
node-internal register() — on the manager created during RLN mount — still
paid the 4s production retry delay on every receipt poll. Apply
withFastRetries() to it, matching the other node-internal managers this
branch already speeds up.
Also reflows setupOnchainGroupManager's sendMintCall to nph after the
Opt.some conversion made during the rebase conflict resolution (master
migrated Option -> Opt while this branch was open).
