Canonical component types, Compare config UI

- Rename parser_hardware.go component type keys to canonical values:
  pcie -> pcie_device, psu -> power_supply
- Update normalizeComponentType to map legacy aliases (pci, psu, dimm,
  ram, processor, network_adapter, etc.) to canonical keys; treat
  "null"/"-" as unknown
- componentTypeTitle handles new canonical keys (pcie_device,
  power_supply)
- Assets list: add Compare config action — opens new window with
  slot-diff and model-count-diff tables for selected servers
- Archive Actions section spec in ui-information-architecture.md
- Add tests: normalizeComponentType aliases, componentTypeTitle aliases,
  FlattenHardwareComponents canonical type keys

 Assets list specifics:
 
 - `All Assets` table filtering is server-side and applies to the full dataset before pagination.
+- `Actions` section includes:
+  - `New Asset`
+  - `Compare config` (opens in a separate window/tab, compares hardware composition for selected servers, shows differences)
+  - `Delete Selected (With Details)`
 - `All Assets` supports global bulk selection:
   - Header `Select` checkbox can select all assets across all pagination pages.
 - Selected IDs persist across page navigation and are stored in browser local storage.
