fix(cli): gracefully handle missing vp fmt during config initialization (#789)

The `vpFmt` function now gracefully handles cases where `vp fmt` is not available or fails to execute. Instead of throwing an error when formatting fails, it now shows a warning message and continues execution. Additionally, the entire formatting operation is wrapped in a try-catch block to handle cases where `vp fmt` is not yet installed (such as during migration processes), allowing the operation to proceed without formatting rather than failing completely.
