fix(dashboard-api): remove broad exception handler from api_status

[bugman-007]

Summary

• Removes broad except Exception: handler from /api/status endpoint
• Complies with CLAUDE.md: "No broad or silent catches"
• Lets errors propagate with full stack traces for debugging

Rationale

The current code catches all exceptions and returns a safe fallback payload to prevent the dashboard from showing "0/17 services". However:

1. This violates the project's error handling philosophy
2. The dashboard has error boundaries that handle failures gracefully
3. Silent fallbacks hide real issues and make debugging harder

Changes

• Removed try/except wrapper from api_status()
• Simplified docstring to reflect new behavior
• Errors now propagate as HTTPException with full context

Test plan

• make lint passes
• Manual test: dashboard loads status correctly
• Manual test: dashboard handles API errors gracefully
• Verify error boundaries catch failures without "0/17" flash
