fix(astrolabe): resolve CI failures for code quality checks

- Fix PHP CS Fixer issues (single quotes, indentation)
- Add typed property declarations to ApiController
- Add Psalm baseline to suppress 517 pre-existing errors
- Fix workflow name references (astroglobe → astrolabe)

The CI workflow was previously watching a non-existent path and never
ran. After fixing the path trigger, these pre-existing code quality
issues were discovered. The Psalm baseline allows CI to pass while
tracking technical debt for incremental resolution.
