Refactor systemctl services and timers

- Unified service templates into generic systemctl templates
- Introduced reusable filter plugins for script path handling
- Updated path variables and service/timer definitions
- Migrated roles (backup, cleanup, repair, etc.) to use systemctl role
- Added sys-daemon role for core systemd cleanup
- Simplified timer handling via sys-timer role

Note: This is a large refactor and some errors may still exist. Further testing and adjustments will be needed.

+# Core Daemon Reset
+
+## Description
+
+This role resets and cleans up all **Infinito.Nexus** core daemon `systemd` service units that match the configured suffix (`SYS_SERVICE_SUFFIX`).  
+It is primarily used in maintenance or reset scenarios when a full service cleanup is required.
+
+## Overview
+
+When the `MODE_RESET` flag is enabled, the role will:
+
+1. **Run Once Per Play:** Guarded by `run_once_sys_daemon` to avoid duplicate execution.
+2. **Identify Service Units:** Finds all `/etc/systemd/system/*{{ SYS_SERVICE_SUFFIX }}` units.
+3. **Stop and Disable Services:** Gracefully stops and disables matching services.
+4. **Remove Unit Files:** Deletes the corresponding unit files from the system.
+5. **Reload systemd:** Ensures the service manager state is updated after cleanup.
+
+## Purpose
+
+The main goal of this role is to ensure a clean and consistent state for core daemon services by removing obsolete or stale systemd units.  
+This is particularly useful when re-deploying or performing a full environment reset.
+
+## Features
+
+- **Automated Cleanup:** Stops, disables, and removes targeted systemd units.
+- **Idempotent Execution:** Runs only once per playbook run.
+- **Configurable Targeting:** Matches services using `SYS_SERVICE_SUFFIX`.
+- **Systemd Integration:** Reloads daemon state after changes.
