ci: Add advanced profile to CI smoke tests (#105)

- Add 'advanced' profile to profile-smoke-test matrix
- Ensures all 5 profiles (essential, developer, business, full, advanced) are tested
- Would have caught issue #103 (malformed URL errors in advanced profile)

Why this matters:
- Advanced profile has 117 components (most comprehensive)
- Previous CI only tested 4 of 5 profiles
- Bug in advanced profile went undetected until manual testing
