feat(ui): port retail selected-item mana

Browse source 
Parse and route the complete 0x0264 guid/fraction/valid response, send exact 0x0263 item-mana queries, and reproduce retail meter visibility plus guid-zero cancellation for mana and health selection changes. Keep the behavior in Core state and the retained selected-object controller with wire/state/UI conformance coverage.
