invalid Dream Skin theme id

Error message

invalid Dream Skin theme id

What it means

Generic guard at the top of load_stored_dream_skin_theme: the theme id argument failed valid_theme_id (format/safety check), so it cannot be used to build a safe directory path. The offending input is the id string passed by the caller (UI, import, or rename flow).

Solutions

1. Pass a theme id that passed validation when the theme was created
2. Avoid hand-editing theme ids or constructing them from user input
3. List existing themes to get a valid id
