Keycloak never reliably ran (fiddly reverse-proxy/hostname config) and the
repo has standardized on Authelia for SSO + 2FA. This rips Keycloak out
entirely:
- Delete the install block, whiptail menu entry, uninstall plumbing, and
EXISTING_SERVICES detection from both 24.04 and 26.04 scripts
- Delete docker-compose-keycloak.yml, fix-keycloak-proxy.sh, and
KEYCLOAK-SETUP-GUIDE.md
- Remove the Keycloak block from caddy-setup-helper.sh
- Update docs (CADDY-FAIL2BAN-SETUP.md, SECURITY-IMPROVEMENTS.md,
NEW-SCRIPT-STRUCTURE.md, SCRIPT-FLOW-INTRO.txt) to reference Authelia
Also documents the fail2ban/Authelia overlap: Authelia handles failed-login
regulation (per-account lockout); the Caddy fail2ban jail is complementary
firewall-level IP banning. Neither does geo-blocking — noted CrowdSec / Caddy
GeoIP as the path for that.

Authelia's installer auto-injects the (authelia) snippet and auth portal
block into the Caddyfile. Moving Caddy first means that injection works
in a single fresh install run without manual follow-up.

The working authelia-setup repo uses the Authelia 4.38+ password
hashing config format with a nested argon2 block and variant key.
The previous version used the old flat format which is rejected by
Authelia 4.39.20 validation. Fix both 24.04 and 26.04 scripts.
Before (broken):
password:
algorithm: argon2id
iterations: 3
...
After (correct for 4.38+):
password:
algorithm: argon2
argon2:
variant: argon2id
iterations: 3
...

- Rename ubuntu-post-install.sh → ubuntu-post-install-24.04.sh to match 26.04 naming convention
- Add --allow-server-ssh systemd override to 24.04 NetBird install (already in 26.04)
- Add full Authelia install block to 26.04 (matching what was added to 24.04)
- Whiptail menu, uninstall, detection, default vars, parse flags, install block
- Both scripts now identical in Authelia and NetBird SSH behavior
