Read template health, charges and flags through the bridge

Consumers of the legacy ItemTemplate combat_health_full,
item_initial_charges and item_flags now read getCombatHealthFull(),
getItemInitialCharges() and getItemFlags() on template.cacheTemplate.
No consumer read the template's combat_health_current; the
combat_health_current reads are the Item's own field.

Parity (offline, scripts/p14.py, 7586 templates): 0 differences in
combat_health_current, combat_health_full, item_initial_charges and
item_flags ("None" dropped on both sides). No value changes expected.

JSON-Refactor-Plan Task 1.4.
