deps: bump mix-rln plugin to feat/lez-rln-stateless (ba32e9f)

Bumps the nimble pin from upstream PR #9 tip (logos-co@61ee3e5) to our
combined branch adklempner/feat/lez-rln-stateless@ba32e9f, which is
PR #9 stateless RLN + our 4 LEZ-RLN commits cherry-picked on top:
- LEZ-backed RLN spam protection (OnchainLEZGroupManager)
- try/except cleanup around await in pollLoop
- info-level proof markers + atomic root+proof refresh
- defensive add of witness-implied root at proof-gen time

The nimble.lock checksum will be re-validated on first build; if it
mismatches we'll update with the value nimble reports.
