[IKatsuba]

This pull request includes significant changes to the apps/api directory, focusing on refactoring route imports, adding middleware for locale handling, and updating route handlers to use the new middleware. The most important changes include moving route files, creating a new middleware for initializing the Faker instance, and updating route handlers to use the context variable for Faker.

Route refactoring:

• apps/api/main.ts: Changed the import paths for all route files to use the routes directory instead of the previous structure.
• apps/api/main.ts: Updated the Hono instance to use a new HonoEnv type and renamed the instance from faker to fakerApi.

Middleware addition:

• apps/api/middlewares/init-faker.ts: Added a new middleware to initialize the Faker instance with locale support based on the Accept-Language header.

Route handler updates:

• apps/api/routes/airline.ts: Updated all route handlers to use c.var.faker instead of directly importing faker. [1] [2] [3] [4] [5] [6] [7] [8]
