[Feature]: Tailor Exception Data for Emily API Errors

[AshtonStephens]

Feature - Tailor Exception Data for Emily API Errors

1. Description

Remove internal exception data from Emily API error responses.

1.1 Context & Purpose

We introduced error handling in Emily that would provide the exception data from the Emily API in the message output of the Server error. This is too much information for a client but we left it in because we're the ones who will see this in the short term and it'll be useful for debugging.

This ticket is to remove that level of detail from the Emily client before launch.

2. Technical Details:

2.1 Acceptance Criteria:

• Emily API no longer provides any exception data in server messages.

3. Related Issues and Pull Requests (optional):

• 72 deposit api mock outputs for api events #124
