ansible: add 'monitor' role mirroring live monitor.vntx.net (Icinga2 + Web 2)
Codifies the bare-metal Icinga2 master + Icinga Web 2 stack on
monitor.vntx.net (Ubuntu 22.04, Apache + mod_php, MariaDB 10.6, Icinga
2.16, IDO-MySQL backend). Re-running the role against the live host
should produce a near-identical configuration.

Role includes:
- Icinga apt repo + full package set (icinga2, ido-mysql, icingaweb2,
  monitoring-plugins, nagios-plugins-contrib, php + apache deps).
- MariaDB DB + user provisioning for both icinga2 (IDO daemon) and
  icingaweb2 (UI), plus a separate read-only `icinga` user that the UI
  uses to read the IDO. Schema bootstrapped only on first install.
- Templated icinga2 config (constants/zones/icinga2.conf), features-
  enabled symlinks (api/checker/command/ido-mysql/mainlog), and the
  three secret-bearing conf.d files (api-users, pagerduty x2) wired to
  vault vars.
- 23 dormant conf.d/* host + service definitions copied verbatim under
  files/. The live install has `include_recursive "conf.d"` commented
  out (a node-setup CLI artifact); role mirrors that. Set
  `icinga2_load_confd: true` in host_vars to rehydrate them.
- Icinga Web 2 ini files (config/auth/groups/roles/modules) + templated
  resources.ini for DB credentials. monitoring module enabled via
  symlink. icingaweb2 admin user bootstrapped on first install via a
  one-shot insert into icingaweb_user (gated on schema-not-yet-imported).
- Apache rewrite + ssl modules. Vhost itself is left to certbot --apache
  (Let's Encrypt cert is operator-managed, role doesn't manage it).

Cluster-wide cleanup:
- Gut roles/general/tasks/debian/icinga2.yml down to the uninstall
  safety net (kept the sweep that removes icinga2 from non-monitoring
  hosts). The previous master-side install + cert-distribution tasks
  referenced templates that never existed in the role; the new monitor
  role replaces them properly.

Operator action before first apply:
- Create host_vars/monitor.vntx.net/vault.yml with the seven required
  secrets (see roles/monitor/README.md). Live values can be pulled from
  /etc/icinga2/conf.d/{api-users,pagerduty-*,ido-mysql}.conf and
  /etc/icingaweb2/resources.ini on the live host.
- Generate the icingaweb2 admin password hash via
  `php -r 'echo password_hash("plaintext", PASSWORD_DEFAULT);'`.
- Run --check --diff before applying; the role is meant to be idempotent
  but hasn't been verified against the live install.
