feat(server): add server metadata collection and display

Add ability to gather and display server system information including OS, architecture, kernel version, CPU count, memory, and uptime. Includes:
- New gatherServerMetadata() method to collect system details via remote commands
- New refreshServerMetadata() Livewire action with authorization and error handling
- Server Details UI section showing collected metadata with refresh capability
- Database migration to add server_metadata JSON column
- Comprehensive test suite for metadata collection and persistence
