Compare and locate hazard groups

Compare and locate hazard groups.

Field	Value
Operation ID	OP-013
Trigger	A caller checks equality, looks up by key, or removes a hazard group.
Inputs	Hazard-group object or hazard-group id
Outputs	Boolean match, collection item, or removal side effect
Primary components	clsHazardGroup
Entry point	Business\SAIF.Business.Policy\clsHazardGroup.vb

Steps

1. Compare hazard groups by HazardGroupID only in the object equality and hash-code methods.
2. Traverse the collection linearly in ItemByKey, Contains, and Remove overloads to find the matching object.
3. Reuse the same identity semantics for deleted-item scans and keyed removal paths.
4. Apply related business rules: BR-POL-016
