The upstream NixOS crowdsec module fails on first deploy ("no API client
section in configuration") because it doesn't auto-register LAPI
credentials. The rewrite in NixOS/nixpkgs#446307 (TornaxO7's branch) adds
a setup oneshot that runs `cscli machines add --auto` if the credentials
file is missing, and handles DynamicUser StateDirectory permissions
explicitly. The bouncer rewrite gets matching auto-registration.
Vendor both module files locally and disable the upstream copies. Drop
modules/crowdsec/ and the disabledModules+imports lines once the PR
merges into nixpkgs unstable.
Config moves to the new unified `settings` API (no more separate
`localConfig`); LAPI moved to 127.0.0.1:8081 to dodge the qBit collision.

Enables the CrowdSec agent with sshd/nginx/http-cve hub collections,
acquires logs from nginx, sshd, and Authelia journald, and wires the
firewall bouncer to enforce bans via nftables. Alerts are POSTed to a
self-chosen ntfy.sh topic (URL read from /var/secrets/ntfy-url, falls
back to a placeholder so the repo stays eval-clean without the secret).
Module is self-contained — remove the file + import to uninstall; state
lives under /var/lib/crowdsec.

Replaces the incomplete nixpkgs NixOS module with the official
CrowdSec Docker image for the LAPI, while keeping the firewall
bouncer as a native systemd service. API key is read from
/var/lib/secrets/crowdsec-bouncer-key at start time so it
never enters the Nix store.
