feat(payments-next): Replace console logging calls with LoggerService

[david1alvarez]

Because:

• LoggerService provides better metadata and consistent log levels across the application than the console logs permit

This commit:

• Replaces console calls with LoggerService in NestJS services, Next.js route handlers, and server actions
• Adds an optional logger parameter to type-cacheable cache strategies, defaulting to console to preserve existing behavior

Closes #PAY-2131
