Fix tables width to use full window width

[mirhamasala]

Feature Description

Make the tables use the full width of the browser window instead of showing unused white margin space.

Problem It Solves

Currently, the table shows horizontal scrollbars even when the window is very wide, while large white margins remain unused on the left and right sides. This wastes valuable screen space and creates an unnecessarily poor user experience.

Proposed Solution

Adjust the table layout to:

• Use full available window width
• Remove unnecessary left/right margins
• Eliminate horizontal scrollbars when there's sufficient space
• Consider responsive breakpoints for different screen sizes

Alternatives Considered

• Fluid width with max-width constraint
• Full-width with proper padding
• Container-based width management

Additional Context

This is part of the Service Provider table mechanics wishlist tracked in #139.
