Three duplicate ErrorSeverity enums (data/error.rs, data/validation.rs, database/error.rs) with variants Low/Medium/High/Critical now use the canonical definition in common::error::ErrorSeverity. Extended common's ErrorSeverity with Low, Medium, High variants (alongside existing Debug, Info, Warn, Error, Critical) and added PartialOrd/Ord derives so both severity models coexist in a single type.
