feat: improve first app launch experience

[kamilbaczek]

📋 Description

This PR improves the first-run experience for developers and simplifies testing and launching the solution.

🛠️ Database Connectivity:
Previously, when running the solution locally, the database connection failed due to an alias that only worked in Docker. This is now resolved—both local and Docker environments work without any additional configuration.

🌐 Swagger Availability:
Before, Swagger had to be manually located. Now, it opens automatically when navigating to the application’s root URL.

📦 PR Includes
• Improved local + Docker setup for DB connection 🔧
• Automatic Swagger UI launch 🌐

Manual Tests
