fix(catalogs): update reconcile ordering and preserve validation failed conditions

[abhijith-darshan]

Description

• sources check (if no sources then initiate orphan resource deletion) early exit
• validate sources (early exit)
• initiate orphan resource deletion (if any) (exit on error)

This PR ensures that the above reconciling functionalities should preserve their errors, messages and reasons when encountered and not be replaced by the generic "not all catalog objects are ready"
