🔄 [MEDIUM] v1 API Lottery Route Points to v2 Implementation

[ayomideadeniran]

Description

In backend/src/routes/api.js, the v1 lottery router is mapped to the v2 lottery implementation.

Location

backend/src/routes/api.js line 49:

v1Router.use(/lottery, v2Lottery);

Impact

• API versioning is misleading: consumers calling /api/v1/lottery/ get v2 behavior
• If v1 and v2 diverge in the future, this will cause unexpected behavior changes
• Clients relying on v1 stability may break when v2 changes

Required Fix

Either:

1. Create a separate v1 lottery implementation and use it here
2. Or, if the lottery implementation is identical for v1/v2, document this decision clearly
3. Add a deprecation notice for the v1 endpoint if it should be migrated to v2
