slides(tappaas): session details, dev-topology slide, identity login
Date 24 August; the demo environment is lab1 (zone lab1, lab1.makerfloss.eu outside / lab1.internal inside). Adds the upstream 'developing TAPPaaS modules' topology from tappaas.org ahead of our own repo picture, which now carries forgejo.makerfloss.eu and highlights that this site tracks main, not stable. Drops the manager-verbs slide; the demo slides carry the verbs where they are actually used, with network/environment/module status commands. Cockpit now logs in via identity:identity rather than a local PAM password, and identity hand-out uses 'authentik-manager user-recovery-link' so no password is ever read aloud. NOTE: podman.json in Community does not yet declare identity:identity — the module needs that change before the session.

desired state; controllers push it into OPNsense, Proxmox, the switch, Authentik.
