docs: reflect live koopa state (inventory + exchange-ansible)

Capture what is actually running on host koopa: podman names/ports,
Caddy vhosts, and hernani paths. Authoritative snapshot:
host/overview/LIVE.md.

Rename docs to live container taler-hacktivism-exchange-ansible
(not the short taler-exchange-hacktivism label). Add public-only
mirror of ~/ansible-taler-exchange deploy helpers (no secrets.yml).
