Feat & Fix: implement File Telemetry, restore DB history, and stabilize production

- Added File Operations Collector (Plan A) for Windows endpoints
- Restored historical server DB via merging and moved to durable /var/lib/activitywatch path
- Forced XDG_DATA_HOME and XDG_CONFIG_HOME for aw-server-rust in environment and systemd
- Updated Ansible playbooks to handle new file collector and durable server paths
- Added DB merge and backup-restore automation scripts
- Fixed CORS and RU WebUI persistence in production deployment
