Need the ability to update a counter to a new value

[Hoperrs]

As a user, I need the ability to update a counter to a new value, So that I can correct any errors or adjust the count when needed.

Details and Assumptions

• Users should be able to specify a new value for the counter.
• The counter can be updated at any time without needing to restart the service.
• The service should validate the new value before applying it (e.g., it must be a non-negative integer).

Acceptance Criteria

Given the counter has a value of 10
When I make a call to update the counter value to 15
Then the counter should return 15 as the updated value
