Items: keep health chargers visible, add charger diagnostics

The health charger's candidate m_iJuice offset (0x3c8) read 0 on a full
charger, so the empty-hide made health chargers disappear entirely. Restrict
the hide to suit chargers (verified 0x47c) until the health offset is
confirmed; health chargers stay visible.

Classify with the server class name when the client class is generic, accept
`healthcharger` in the health branch (maps use item_healthcharger /
CNewWallHealth, not the func_healthcharger brush), and log up to eight
`juice:` lines with the class and both candidate offsets/values.
