Fix objscale_master build after upstream master merge

[Rochet2]

Summary

The scheduled merge workflow merges TrinityCore/TrinityCore master into objscale_master and builds with -DWITH_WARNINGS_AS_ERRORS=1. The branch was failing at the merge step (spawn SQL conflicts) and would not compile after upstream schema/API changes.

This PR merges the latest upstream master into objscale_master, resolves the conflicts, and keeps per-spawn scale persistence working.

What was wrong

Merge conflicts

1. WorldDatabase.cpp — Upstream expanded WORLD_INS_CREATURE / WORLD_INS_GAMEOBJECT with phaseUseFlags, terrainSwapMap, ScriptName, and StringId. Objscale adds a per-spawn size column to both INSERT statements.

2. Creature.cpp::SaveToDB — Upstream appended ScriptName / StringId SQL binds after unit flags. Objscale appends data.size at the end of the same statement.

3. GameObject.cpp::SaveToDB — Same overlap between objscale's data.size bind and upstream's ScriptName / StringId binds.

Post-merge compile errors (WITH_WARNINGS_AS_ERRORS=1)

4. cs_gobject.cpp::HandleGameObjectSetScaleCommand — Passed GameObjectSpawnId through std::to_string(...).c_str() for LANG_COMMAND_OBJNOTFOUND instead of dereferencing like other call sites; success message passed std::string to a %s placeholder without .c_str().

What was fixed

File	Fix
src/server/database/Database/Implementation/WorldDatabase.cpp	Keep upstream spawn columns and objscale size in both INSERT templates.
src/server/game/Entities/Creature/Creature.cpp	Bind data.size, then upstream ScriptName / StringId.
src/server/game/Entities/GameObject/GameObject.cpp	Same bind ordering for gameobjects.
src/server/scripts/Commands/cs_gobject.cpp	LANG_COMMAND_OBJNOTFOUND, *guidLow; .ToString().c_str() for the success %s.

Test plan

• Merge this PR into objscale_master.
• Confirm the merge workflow _master (objscale_master, …) jobs pass.
• In-game: .npc scale 2.0 on a creature — verify scale and DB persistence.
• In-game: .gobject set scale <id> 2.0 — verify scale, persistence, and visibility refresh.
• Reset path: scale <= 0 restores template scale.
