Validate path input in add-token/remove-token commands and prompt user for correction if unrecognized

[alimand]

Currently, when running the add-token or remove-token command, if an incorrect "path" is entered (e.g., collection/stations instead of the correct collections/stations), the command still executes without returning an error. This lack of validation can lead to unintended behavior or misconfigurations.

Should enhance the command by implementing path validation to check if the provided path is recognized. If the path is invalid, prompt the user to re-enter it instead of proceeding with execution.
