fix(mcp): improve API key status messaging

- Show when API key is configured instead of misleading 'not set' message
- Add informative message when server has API key configured
- Applies to both setup-claude-code-mcp.sh and fix-mcp-servers.sh

Previously would show 'Skipping exa (EXA_API_KEY not set)' even when
the key was set. Now correctly shows the key is configured.
