fix: login fallback error

[Chisomchima]

Implements DHIS2-18585

Description:

This pull request addresses an issue with the login page where the dynamic base URL was not considering the URL context path (e.g., /dev, /prod). Without this fix, the application attempted to send the authentication request to the wrong endpoint (/api/auth/login instead of /dev/api/auth/login), leading to a failure when hosted under specific context paths like /dev.

Changes:

• Base URL Calculation:
  • Updated the getBaseUrl() function to account for the context path (e.g., /dev, /dev-2-41, etc.) in the URL.
  • The context path is now correctly appended to the API endpoint, ensuring that requests like POST /api/auth/login are sent to /dev/api/auth/login when the app is hosted under /dev.
  • If the page URL ends with login.html, that part is correctly stripped off while preserving the context path.

Problem Addressed:

• Before this change, when the app was hosted under a context path (e.g., /dev/login.html), the login form submitted requests to http://localhost:8080/api/auth/login instead of the expected /dev/api/auth/login.
• This caused authentication requests to fail for applications hosted in a subdirectory or versioned environment.
