feat: Add custom system parameters for x-hwid header (#1027)

- Add sub_custom_hwid_params field to DataStore
- Add UI text field for entering custom parameters
- Parse and apply custom parameters when sending HWID headers
- Format: hwid=value,os=value,osVersion=value,model=value
- Empty input uses default system parameters
