Refactor: migrate cmp/* and srv/* roles into sys-stk/* and sys-svc/* namespaces

- Removed obsolete 'cmp' category, introduced 'stk' category (fa-bars-staggered icon).
- Renamed roles:
  * cmp-db-docker → sys-stk-back-stateful
  * cmp-docker-oauth2 → sys-stk-back-stateless
  * srv-domain-provision → sys-stk-front
  * cmp-db-docker-proxy → sys-stk-full-stateful
  * cmp-docker-proxy → sys-stk-full-stateless
  * cmp-rdbms → sys-svc-rdbms
- Updated all include_role references, vars, templates and README.md files.
- Adjusted run_once comments and variable paths accordingly.
- Updated all web-app roles to use new sys-stk/* and sys-svc/* roles.

+# Database Docker Composition
+
+This role combines the central RDBMS role (`sys-svc-rdbms`) with Docker Compose to deliver a ready-to-use containerized database environment.
+
+## Features
+
+- **Central RDBMS Integration**  
+  Includes the `sys-svc-rdbms` role, which handles backups, restores, user and permission management for your relational database system (PostgreSQL, MariaDB, etc.).
+
+- **Docker Compose**  
+  Utilizes the standalone `docker-compose` role to define and bring up containers, networks, and volumes automatically.
+
+- **Variable Load Order**  
+  1. Docker Compose variables (`roles/docker-compose/vars/docker-compose.yml`)  
+  2. Database variables (`roles/sys-svc-rdbms/vars/database.yml`)  
+  Ensures compose ports and volumes are defined before the database role consumes them.
+
+The role will load both sub-roles and satisfy all dependencies transparently.
+
+## Task Breakdown
+
+1. **Set Fact** `database_application_id` to work around lazy‐loading ordering.
+2. **Include Vars** in the specified order.
+3. **Invoke** `docker-compose` role to create containers, networks, and volumes.
+4. **Invoke** `sys-svc-rdbms` role to provision the database, backups, and users.
