feat(db): implement options pattern for database connection strings

[kamilbaczek]

• Introduce IOptions to fetch configuration data instead of leveraging IConfiguration abstraction. This makes options easier to maintain and validate. ⚙️

Pull Request Overview

This PR implements the options pattern for database connection strings across all modules, replacing direct configuration access with strongly-typed options classes that include validation.

• Introduces persistence options classes for each module (Reports, Passes, Offers, Contracts) with required connection string properties
• Updates database connection factories and modules to use IOptions pattern instead of direct IConfiguration access
• Adds validation on startup to ensure connection strings are properly configured
