Add detailed hardware configuration view with sub-tabs

- Redesign config page with tabs: Spec, CPU, Memory, Power, Storage, GPU, Network, PCIe
- Parse detailed memory info from component.log with all fields:
  Location, Present, Size, Type, Max/Current Speed, Manufacturer, Part Number, Status
- Add GPU model extraction from PCIe devices
- Add NetworkAdapter model with detailed fields from RESTful API
- Update PSU model with power metrics (input/output power, voltage, temperature)
- Memory modules with 0GB size (failed) highlighted in warning color
- Add memory overview stats (total GB, installed count, active count)
