fix: use correct ErrorCode values for InvalidParameter, FeatureNotEnabled, and NotSupported

[oniani1]

Fixes #983

Three error factory functions use the wrong ErrorCode enum value:

• ERRORS.InvalidParameter used ErrorCode.MissingParameter (affects 18+ call sites)
• ERRORS.FeatureNotEnabled used ErrorCode.InvalidRequest (affects 28+ call sites)
• ERRORS.NotSupported used ErrorCode.InvalidRequest (affects 1 call site)

All three correct enum values already exist but were never referenced. One-line fix each.
