(Task 1) Feature: filter Races by Visible

[Cuttsy27]

Changes

• added optional bool visible to proto filter message
• updated applyFilter to add clause to sql string if visible is not null
• added tests for the applyFilter method
• added tests for the racing service

Summary

To filter by a Race's Visible property, we add the optional bool visible property to the ListRacesRequestFilter protobuf message. The property is optional because both true and false are valid values for the visible property and we can use nil to determine if the filter is set, then filter by visible = true or visible = false races.

Example

curl -X "POST" "http://localhost:8000/v1/list-races"
-H 'Content-Type: application/json'
-d $'{
"filter": { "visible": true }
}'

Tests

• We test the updated applyFilter method on the races repo for 100% coverage.
• We test the racing service by mocking the races repo to ensure it correctly handles race filtering.
