Housing: Fix entity GUID mismatch, initiative wire format, and packet error fields

Fix Housing/4 NeighborhoodMirrorEntity GUID using battlenetAccountId instead
of the neighborhood's actual DB low GUID. The client matches entity GUIDs
against NeighborhoodGUID references in JamCliHouse packets — a mismatch
causes the client to fail to associate plot data with the correct entity.
Added ResetGuid() to correct the GUID in Player::LoadFromDB before the
entity is added to the world.

Fix initiative SMSG_GET_PLAYER_INITIATIVE_INFO_RESULT: duration now converts
DB2 days to seconds (×86400), progress scales from 0.0–1.0 to 0–1000 wire
format, and the packet is sent proactively on service status check so the
client's isLoaded flag gets set.

Revert incorrect HasError replacements on 14+ non-initiative response packets
back to their proper Result field assignments. Remove fake initiative SQL
hotfix data that overwrote real DB2 records.
