Fix linting issues: quote type casts, extract token constant, sort imports, use named logger

[Copilot]

Addresses linting violations flagged in code review: type annotation quoting (TC006), hardcoded token type (S105), import ordering (I001), modern union syntax (UP045), and root logger usage (LOG015).

Changes

• app/auth/jwt.py: Quote type cast expressions per TC006

  # Before: cast(str, jwt.encode(...))
  # After:  cast("str", jwt.encode(...))

• app/schemas.py: Extract TOKEN_TYPE_BEARER = "bearer" constant to resolve S105 security warning

• app/routers/operator.py:

  • Sort imports (stdlib before third-party)
  • Replace Optional[InvoiceRequest] with InvoiceRequest | None (PEP 604)

• app/config.py: Use logging.getLogger(__name__) instead of root logger

All ruff checks pass.

Closing this PR. It is now outdated after the full system refactor completed in December 2025.

The project has been unified under a new architecture, updated dependencies, and a consistent configuration model.

Keeping this PR open would introduce inconsistencies and no longer provides technical value.
