Add Lora display names for Power Lora Loader

[pigeonsupport]

Summary

Adds an optional Display Name field for Loras in the info popup.

When a display name is set, the Power Lora Loader shows that name instead of the raw filename. If the field is empty or missing, it falls back to the existing filename behavior.

Details

• Adds a new editable Display Name row to the Lora info popup.
• Stores the value in the existing rgthree metadata file as displayName.
• Does not rename or modify the actual Lora file.
• Keeps existing workflows and metadata files backwards compatible.
• Refreshes the Power Lora Loader label after metadata is loaded or saved.
• Clears cached Lora info when switching to a different Lora.

Compatibility

This is backwards compatible. Existing metadata files without displayName continue to work normally and the loader will keep showing filenames by default.
