feat(auth): add authentication routes and user token handling

- Implemented user authentication routes in `auth.ts` for fetching current user info and admin verification.
- Added caching mechanism for user tokens to improve performance.
- Created middleware for admin authentication.

feat(opencode): create OpenCode client route

- Added `opencode-cnb` route for creating OpenCode clients with session management.
- Integrated OpenCode SDK for client operations and session handling.

refactor(client): encapsulate OpenCode client creation

- Created a utility function `getClient` in `client.ts` to initialize OpenCode clients.

test(opencode): add tests for OpenCode routes

- Implemented test cases for OpenCode routes in `list.ts` to validate functionality.
- Created common utilities for testing in `common.ts`.
