Mix Space Code Review

Review code for project conventions. Target: $ARGUMENTS

Review Checklist

1. Controller Conventions

• Uses @ApiController() instead of @Controller()
• Paginated endpoints return PaginationResult<T> from repository (no special decorator needed)
• Authenticated endpoints use @Auth() decorator
• Uses correct HTTP methods (GET/POST/PUT/DELETE)
• Parameter validation uses @Body/@Query/@Param({ schema }) with Zod schemas
• Return values follow response conventions (arrays auto-wrapped, objects returned directly)

2. Service Conventions
