Add DPS calculations and columns to WeaponTable

Introduced new methods in `EntityWeaponModel` to calculate DPS for normal, light, medium, and heavy damage types. Updated `WeaponTable.razor` to display these new DPS values as additional columns for better weapon performance insights. Also fixed missing initialization of the base `Damage` property in test data.
