configs: rename dirs to match live koopa containers

Reflect host naming in git paths:
- configs/taler-hacktivism/ (was taler-merchant) → container taler-hacktivism
- configs/taler-hacktivism-bank/ (was taler-bank) → container …-bank,
  image taler-hacktivism-banking:live
- configs/taler-exchange-ansible/ already matches …-exchange-ansible
- configs/taler-exchange/ = conf inside that exchange container

Update LIVE.md, README, ports/refs. No secret values.
