refactor(server): refactor structure and implement to Hono framework

- Updated cache utility to use new type definitions from hono-types.
- Added TestCacheImpl for testing purposes, providing a simple in-memory cache implementation.
- Removed outdated integration tests and replaced them with a more modular test setup using Hono.
- Created a new Hono app factory to initialize the application with middleware and services.
- Introduced middleware for lazy initialization of dependencies, JWT handling, and request timing.
- Defined types for Hono context and variables to improve type safety across the application.
- Implemented error handling and 404 responses in the Hono app.
- Updated test API client to align with the new Hono structure and provide type-safe API calls.
