Description

This PR fixes alignment issues in the shared website styles used by the listing pages.

Changes:

• align resource action buttons so the Install dropdown, icon buttons, and GitHub button share consistent sizing and vertical alignment
• allow resource action controls to wrap cleanly in narrower layouts
• bottom-align wrapped filter controls so filter rows do not appear staggered

The change is limited to website/src/styles/global.css and does not add or modify any instructions, agents, skills, plugins, or workflows.
