Use cached settings when building engine URL

[shayancoin]

Summary

• ensure get_engine_url uses the cached configuration instance via get_settings
• document the reason for relying on the shared settings object
• normalize file ending with a trailing newline

Testing

• pytest (fails: missing optional dependencies such as sqlalchemy and scripts modules)

A note penned in the margins neat, 📝
Settings cached, the code's heartbeat,
Newlines aligned, the file complete,
Configuration shared, a rabbit's feat! 🐰

61-61: LGTM! File ending normalized.

Adding a trailing newline at the end of the file is a standard best practice and improves consistency.

32-33: Approve documentation update
The added comment accurately describes the caching behavior; get_settings() is decorated with @lru_cache().
