Classic 1.12 SMSG_INSPECT (wire 0x115): parse PackedGUID + 19×uint32
itemEntries to populate InspectResult and inspectedPlayerItemEntries_ cache,
enabling gear inspection of other players on Classic servers. Triggers item
queries for all filled slots so the inspect window shows names/ilevels.
SMSG_ITEM_ENCHANT_TIME_UPDATE: parse itemGuid/slot/durationSec/playerGuid and
store per-slot expire timestamps in tempEnchantTimers_. Fires 5min/1min
chat warnings before expiry. getTempEnchantRemainingMs() helper queries live
remaining time. Buff bar renders timed slot buttons (gold/teal/purple per
slot) that pulse red below 60s — useful for Shaman imbues, Rogue poisons,
whetstones and oils across all three expansions.
