refactor: move list_prompts to prompts module completely (#1468)

- Renamed `prompt.lua` to `prompts.lua` for clarity and consistency.
- Moved prompt listing logic from `init.lua` to `prompts.lua`.
- Updated all references to use the new `prompts` module.
- Removed unused model and prompt listing functions from `init.lua`.
