feat: Use chassis serial number as configuration output filename

Instead of using a static filename, the server configuration is now saved
using the server's chassis serial number. This helps identify which
configuration belongs to which physical server and prevents accidental
overwrites when collecting data from multiple servers.

Changes:
- Added filename sanitization function to handle invalid characters
- Replaced static server_config.toml with dynamic {serial_number}.toml
- Updated user feedback messages to show actual filename being used

Example output: ABC123DEF456.toml instead of server_config.toml
