Fix: Ensure CSS paths include hostname for remote module styles

[viguenstepanyan]

Description

This PR fixes an issue with CSS loading in remote modules where styles were being loaded from incorrect URLs missing the hostname. Previously, when loading remote module styles, the URLs were constructed without the proper hostname (e.g. //assets/style.css instead of http://hostname/assets/style.css).

The fix improves URL construction logic by:

• Properly handling both absolute and relative base URLs
• Preserving hostname when constructing style URLs
• Adding utility functions for consistent path trimming
• Ensuring proper URL joining for remote module styles

Additional context

The issue was particularly visible when:

1. Loading remote module styles in production builds
2. Using base URLs other than root ('/')
3. Working with cross-origin remote modules
