AI Summary: Improve the user interface of the RoboSats application to display informative error messages to the user when invoice routing fails due to insufficient payment per million (PPM). The current implementation silently fails, requiring users to inspect the browser's developer console to understand the error. The solution involves capturing and displaying the API error message within the application's UI, likely using a toast notification or similar mechanism.

AI Summary: Modify the RoboSats application to display the client's calculated limitations alongside the coordinator's limitations in the coordinator profile. This involves calculating the client's limit and adding it to the existing display of the coordinator's limit.
