Overview

This PR improves the robustness, performance, and maintainability of the RegisterCompanyView by introducing the following key changes:

1. Atomic Transactions: Ensures all database operations for company creation are atomic, preventing partial updates and ensuring consistency.
2. Enhanced File Handling: Adds UUIDs to filenames, checks for the presence of the logo file before saving, and ensures proper cleanup on errors.
3. Improved Error Handling: Provides better error feedback and maintains a clean state by handling specific exceptions and deleting files if necessary.
4. Optimized Manager Assignment: Moves manager filtering and assignment inside the transaction block to optimize performance and avoid unnecessary queries.
5. Validation of Optional Fields: Handles optional fields more gracefully to avoid errors and improve robustness.

These changes ensure that the company registration process is more reliable and efficient.
