Amir Alexander Abdelbaki 4f22a3b03f refactor(ansipa): dev_security-scan → dev_mon_clamscan, report to CheckMK; drop SMB scan pipeline
Rename the security-scan policy to dev_mon_clamscan (fits the XXX_mon_* naming
for monitoring groups) and make it hand results to CheckMK natively instead of
uploading logs to an SMB share.

- dev_mon_clamscan.sh: runs the daily ClamAV/rkhunter/chkrootkit scan and writes
  its own CheckMK local check (ansipa_clamscan → service "Ansipa_ClamScan"); the
  agent from dev_mon_base collects it. Removes the SMB upload entirely. Discovery
  matches dev_mon_clamscan BEFORE the generic dev_mon_* catch-all so it sets
  WANT_CLAMSCAN rather than being treated as a dev_mon.sh check. mkdir -p the
  cron dir (minimal hosts lack /etc/cron.d until cron is installed).
- Remove the now-redundant dev_mon_malware check from dev_mon.sh (subsumed).
- Remove usr_scan-notify and the whole SMB scan-alert pipeline it fed:
  ansipa-fetch-alerts.sh, ansipa-scan-notify.sh, server ansipa-check-scans.sh,
  the ansipa-scans Samba share + scanupload account, /etc/ansipa-smb.creds, and
  the SMB_SCAN_PASSWORD/smb_scan_password variables (playbook, compose, run.sh,
  .env, Dockerfile). The ansipa-luks-keys and ansipa-policystore shares stay.

Verified live on the Arch client: enrolling in dev_mon_clamscan writes the scan
script, cron, and local check (which reports "Ansipa_ClamScan"); leaving the
group removes all three. Docs updated (policy tables, architecture, SMB shares,
scan-flow → CheckMK).

Amir Alexander Abdelbaki b21f415cde fix(ansipa): hostname-binary-free FQDN + push-mode orchestration (NAT path)
Found while running the policy matrix and NAT/WAN scenario in VMs:

- ansipa-enforce-policies.sh and the dev_security-scan generated script called
  `hostname -f`, but the hostname binary (inetutils) is not installed on a
  minimal Arch system, so the enforcer aborted with "hostname: command not
  found" on every run. Add an ansipa_fqdn() helper (hostnamectl / getent /
  /etc/hostname / kernel-hostname fallback chain) and use it; inline the same
  fallback in the standalone scan script.

- Fix two stacked bugs that meant CheckMK push mode — the only monitoring
  transport that works when a client is behind NAT — never functioned:
  * ansipa-checkmk-setup.sh referenced IPA_ADMIN_PASS in the DONE_FLAG
    early-exit path, but that variable was assigned only afterwards, so every
    rerun kinit'd with an empty password, failed silently, and skipped the
    push-mode request writer. Resolve config before the early exit.
  * _write_push_requests parsed `ipa hostgroup-show dev_mon_base` members with
    awk that did `next` on the "Member hosts:" line — but ipa prints members on
    that same line, so the only line with hostnames was discarded and no push
    request was ever written. Rewrite the awk to capture the label line's value
    plus wrapped continuation lines. Verified end-to-end: requests are written
    and CheckMK flips the host to cmk_agent_connection=push-agent.

Amir Alexander Abdelbaki 0f767fb051 fix(ansipa): docker stack volume/network naming, healthchecks, client-routable CMK URL
Found while bringing up the FreeIPA+CheckMK+Keycloak stack in a VM:

- Pin volume and network names (name:) so compose and the cgroup-v2 run.sh
  wrapper share the same objects. Compose otherwise prefixes the project name
  (image_cmk-creds, image_ipa-net), so the run.sh-started freeipa container
  mounted a different cmk-creds volume than the compose-started checkmk wrote
  to — the automation secret never reached IPA and the dev_mon_* integration
  retried forever. run.sh also now labels the network it creates so compose
  adopts it instead of erroring "exists but not created by compose".
- run.sh: mount cmk-creds into freeipa and include checkmk in the "all" target;
  both were missing, so the CheckMK path was never wired up via run.sh.
- Fix both healthchecks: Keycloak has no curl/wget and serves /health on the
  management port 9000 only when KC_HEALTH_ENABLED=true, so the old curl probe
  left it permanently unhealthy — use a bash /dev/tcp probe against 9000.
  CheckMK's /api/1.0/version needs auth (401), so probe the login page instead.
- Advertise a client-routable CheckMK URL (CMK_ADVERTISED_URL) in the
  dev_mon_base description instead of the container-internal 172.30.0.12, which
  enrolled clients cannot reach; falls back to the internal URL when unset.

Amir Alexander Abdelbaki 6bb19cea78 feat(ansipa): integrate CheckMK CE monitoring
Adds full CheckMK CE 2.3 monitoring integration to the ansipa policy
enforcement system. Monitoring is group-driven — adding a host to an
IPA hostgroup installs the relevant agent checks automatically.

New monitoring groups:
  dev_mon_base      — install check-mk-agent, register host in CMK;
                      packages check + built-in CPU/RAM/disk/uptime
  dev_mon_malware   — ClamAV scan results from dev_security-scan log
  dev_mon_timeshift — Timeshift snapshot age (WARN >5d, CRIT >10d)
  dev_mon_power     — CPU package TDP via Intel RAPL or lm-sensors
  usr_mon_logins    — SSH login attempts (success/failed/invalid-user)

Key implementation details:
- ansipa-checkmk-setup.sh: one-time folder/group creation on FreeIPA
  container; reads automation secret from shared cmk-creds volume;
  stores credentials in IPA dev_mon_base description for clients
- ansipa-checkmk.service: starts after IPA first-boot, retries until
  both IPA and CheckMK are ready
- docker-compose.yml: CheckMK container adds port 8000 (agent receiver
  for push mode); command override writes automation.secret to shared
  volume, patches cookie_auth.conf for API access, and polls
  /cmk-creds/push-mode-*.req to configure push-agent hosts in hosts.mk
- ansipa-enforce-policies.sh: local check scripts for all 5 groups;
  cmk-agent-ctl registration + auto push timer when push mode is active
- CheckMK REST API path corrected to /cmk/check_mk/api/1.0/ (not
  /cmk/api/1.0/ which returns 404 in 2.3)
- .gitignore added to prevent accidental commit of .env test creds
