Remove or separate NPCs from contacts

[LuciousLisa]

• Problem: NPCs are listed in contacts with a neutral (0) standing and type 'character'. This is confusing and makes it difficult to differentiate NPCs from actual player added contacts.
• Expected: A button to allow filtering out NPCs, or a type assignment that differentiates them from player characters. Alternatively, remove the NPCs altogether from this page.
• Logs / Screenshots / Proof: Screenshot, showing two actual characters and 3 NPCs.
