Contraband and medical price scanners beep

[whatston3]

About the PR

The medical and contraband price guns now beep, consistent with the base appraisal tool.

The API of both was swapped out from EntityUid, Component to Entity.

Why / Balance

Consistency.

How to test

1. Scan yourself with the contraband tool. Beep. Message should be accurate.
2. Spawn and scan a blood red hardsuit with the contraband tool. Beep. Message should be accurate.
3. Scan yourself with the medical bounty scanner. Beep. Message should be accurate.
4. Spawn an emergency medical pod, scan the occupant. Beep. Message should be accurate.
