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.

**Goal:** when the player selects a world object (LMB pick or Tab/Q combat-target), the action bar's
bottom strip shows that object's **Health meter** + **name**; **Mana meter** for owned items.
**Landed 2026-07-11:** the selected-item mana path is implemented end to end.
`CM_Item::Event_QueryItemMana @ 0x006A8610` pins outbound `0x0263`; inbound `0x0264`
is guid + float fraction + trailing 32-bit valid flag; Core `ItemManaState` feeds
`SelectedObjectController`, which ports valid/invalid visibility and guid-zero cancellation.
**Retail lifecycle** (the oracle): `gmToolbarUI::HandleSelectionChanged`
(`acclient_2013_pseudo_c.txt:198635`) — on selection it `SetVisible(1)`s the right meter and fires
`CM_Combat::Event_QueryHealth(guid)` (creatures/players) or `CM_Item::Event_QueryItemMana(guid)`
