Add container config export/import

[gigachadmma69]

Summary

Allows users to share and reuse container configurations by exporting/importing the settings JSON as a .wcc (Winlator Container Config) file.

Export

• New "Export Config" option in the container popup menu (between Duplicate and Remove)
• Saves to Downloads/Winlator/<container-name>.wcc
• Strips device-specific fields (id, cpuList, cpuListWoW64) that would be invalid on another device
• File is ~1KB and contains all tuning settings (graphics driver, DX wrapper, env vars, box86/64 preset, win components, etc.)

Import

• New import button in the containers toolbar (action bar)
• Opens the system file picker to select a .wcc file
• Creates a new container with the imported settings via the existing createContainerAsync(JSONObject) pipeline
• The pipeline automatically assigns a new ID, creates the directory, extracts the Wine container pattern, and applies all settings

Architecture

• Export reuses the existing .container JSON format — just reads, strips the ID, and writes
• Import reuses the existing createContainerAsync(JSONObject) — zero new container creation logic needed
• Follows the same file picker pattern used by InputControlsFragment for profile import

Test plan

• Open container popup menu → "Export Config" appears
• Export a container → .wcc file appears in Downloads/Winlator/
• Open .wcc file in a text editor → valid JSON with all container settings, no id field
• Tap import button → file picker opens
• Select the exported .wcc file → new container appears with matching settings
• Verify imported container's settings match the exported container
