sync: mirror deployed github repo (chains + sanitized bridge), keep GitLab CI

Make this monorepo's tracked tree identical to the deployed github repo
(github.com/pezkuwichain/pezkuwi-DKS): all RC/AH/People runtimes and framework
carry the mainnet fixes (incl. U128CurrencyToVote everywhere, so the staking
election stall cannot recur), and tools/usdt-bridge matches the current,
public-safe custody tooling (real config/deploy units gitignored, secret-file
locations and server IPs stripped, sanitized *.example templates committed).

Only exception to the mirror: GitLab-native CI is preserved (.gitlab-ci.yml and
.gitlab/), to be rebuilt to match the github CI pipeline in a follow-up.
