"Contract" table improvements
Improvement 1:
Add ordering ascending/descending functionality for all the columns beside Role and Options (like it is implemented for "Tasks" and "Invoices" tables)

Improvement 2: For both Contributor and PO flows, in Contracts table, when pressing on the values from the first column (Project or Contributor), you should display their Tasks and Invoices cards - not when you press on the See Tasks button
Improvement 3:
For Contributor view, in the Contracts table, add the navigation to GitHub in the Option columns as an action button.

Improvement 4:
After implementing Improvement 2 and 3, add a button in the Options column, to navigate to GitHub also from the contracts table for a PO (like you have for Contributor).
When you click on the contributor, you should be redirected to GitHub issues list, where they should be already filtered based on the user and activity type (activity type - after implementing #261 )
