🌟 Feature Description

Enhance the database connection setup by safely encoding sensitive credentials (such as the database password) using urllib.parse.quote_plus. This ensures that special characters in credentials do not break the database connection URL.

🔍 Problem Statement

Currently, database credentials are interpolated directly into the connection string:
DATABASE_URL = f"postgresql+asyncpg://{USER}:{PASSWORD}@{HOST}:{PORT}/{DBNAME}"

If the database password contains special characters like @, :, /, #, or %, the connection string becomes malformed, leading to confusing runtime errors such as:
socket.gaierror: nodename nor servname provided

This issue is hard to debug and commonly occurs with managed databases like Supabase, where passwords often include special characters.

🎯 Expected Outcome

1. Database credentials, especially the password, are safely URL-encoded before being used in the connection string.
2. Prevents connection failures caused by malformed URLs.
3. Improves robustness and developer experience when configuring environment variables.
