refactor: replace hardcoded URL paths with named route references

[IngmarStein]

Replace hardcoded URL strings (e.g., "/", "/auth/edit") with request.url_for() calls using named routes throughout auth.py and manager.py routers. This improves maintainability by centralizing route definitions and eliminates potential bugs from manually updating URLs across multiple files.

Summary of Changes

Hello @IngmarStein, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly refactors the application's URL handling mechanism. It transitions from using static, hardcoded URL paths to a more dynamic and maintainable system that leverages named route references via request.url_for(). This change standardizes how URLs are generated throughout the auth and manager modules, making the codebase more resilient to future route modifications and reducing the likelihood of broken links.

Highlights

• Centralized URL Management: Replaced hardcoded URL strings with request.url_for() calls using named routes across auth.py and manager.py routers.
• Improved Maintainability: This refactoring centralizes route definitions, making the application more robust and easier to maintain by eliminating the need to manually update URLs in multiple locations.
• Test Adjustments: Updated test assertions in test_api.py, test_register+login.py, and test_webp_upload.py to reflect the full http://testserver/ URLs generated by the test client, aligning with the new URL generation approach.
• Dependency Cleanup: Removed an unused settings dependency from the post_register_owner function in auth.py.

Code Review

This pull request is a great refactoring that replaces hardcoded URL paths with named route references using request.url_for(). This significantly improves the maintainability of the codebase. The changes are well-executed across auth.py and manager.py. I've added a few suggestions to further reduce code repetition by reusing RedirectResponse objects, which aligns with the goal of this refactoring.
