chore: move uvicorn port config to env file

[eniiku]

Description

The Uvicorn server port is currently hardcoded in main.py:

if __name__ == "__main__":
    uvicorn.run("main:app", port=7001, reload=True)

This configuration should be moved to an environment file (e.g., .env) to make it more flexible and configurable.

---

Proposed Changes

1. Add a PORT variable to the .env file (update env.sample as well:

  PORT=7001

2. Load the PORT variable from the environment in the Settings class (api/utils/settings.py):

  class Settings(BaseSettings):
  PORT: int = 7001  # Default value if not set in .env

3. Update main.py to read the port from the environment file:

  from api.utils.settings import settings

  if __name__ == "__main__":
  uvicorn.run("main:app", port=settings.PORT, reload=True)

Acceptance Criteria:

• The PORT variable is defined in the .env file.
• The main.py file reads the port from the environment.
• The application runs successfully using the port specified in the .env file.
