feat(ui): share indicator detail panels

Port the authored Link Status, Vitae, and Mini Game detail roots and register every indicator page with retail's one-active gmPanelUI owner. Helpful/Harmful and the new pages now replace Inventory, Character, or Magic at one canonical window position while preserving the DAT restore-previous flag.

Correct the retail ping wire to its payload-free request/response, publish measured RTT, and port Vitae recovery XP from the live modifier and player properties. Keep transport packet-loss averaging and mini-game gameplay explicitly tracked under AP-110.

Release build and all 5,814 tests pass with five intentional skips. Connected visual gate pending.
