feat: add test database setup and usage helpers

- Introduced a new test file for setting up an in-memory SQLite database for testing purposes.
- Added helper functions for seeding test data, including users, plans, subscriptions, and wallet transactions.
- Implemented usage helpers to load user video counts and storage usage.
- Created user payload struct and functions to build user payloads with preferences and wallet balance.
- Refactored gRPC server setup to include new services and handlers.
- Updated proto files to simplify service definitions by removing redundant service prefixes.
