fix: configure log colors

[alexbilbie]

Summary

• add LOG_COLORIZE server env setting
• pass colorize through Django Loguru setup
• add SDK KARRIO_LOG_COLORIZE support, falling back to LOG_COLORIZE
• keep colored logs enabled by default

Impact

Set LOG_COLORIZE=false to disable ANSI-colored server console logs. Set KARRIO_LOG_COLORIZE=false for standalone SDK logs.

Validation

• python3 -m py_compile apps/api/karrio/server/settings/base.py modules/core/karrio/server/core/logging.py modules/sdk/karrio/core/utils/logger.py
• git diff --check

Server/SDK test wrappers not run: local .venv/karrio is missing, so karrio command/env unavailable.
