Fix Dark Fog enemy synchronization on client

[JoshyDo]

This PR addresses several underlying issues causing Dark Fog enemies (specifically ground units and space enemies) to not properly synchronize and render on clients in multiplayer.

The fix targets 7 specific areas:

1. Missing Ground Activation Broadcasts
   In EnemyDFGroundSystem_Patch, the server was not broadcasting activation packets for ground units. Added logic to loop through _activate_unit_list and properly send DFGActivateUnitPacket to clients.

2. Base Alert Wave Sync
   In DFGBaseComponent_Patch, an inverted guard condition (!IsIncomingRequest.Value) was blocking base alert waves on clients. Fixed by ensuring it only returns false if it's a client and not an incoming request.

3. Space Sector Purging
   In SpaceSector_Patch, isCombatMode was uninitialized on clients, causing the game to actively purge valid space enemies via SetEmpty(). Fixed the initialization and added null guards.

4. Client HP/Shield Preservation
   In CombatManager, combatStatId was being reset to 0 for all entities in the pool on load. Added an exception for EObjectType.Enemy to ensure enemy HP and shields are preserved on clients.

5. Recycle Pool Memory Leak / Clobbering
   In EnemyManager, a bug was causing destroyed enemies to overwrite index 0 of the recycle stack (enemyRecycle[0] = enemyId;), destroying the pool queue. Rewrote this to correctly search, append, and resize the recycle arrays.

6. Multithreaded Aggro Sync
   Added [HarmonyPatch(typeof(GameLogic), nameof(GameLogic._enemy_ground_unit_parallel))] to GameTickLogic_Unit_Transpiler to ensure the aggro sync targets the multi-threaded function correctly.

7. Retargeting Crash
   Fixed a minor off-by-one bounds check (<= to <) and added a >= 0 check in DFGRetargetProcessor to prevent IndexOutOfRangeException errors.

(Note: These changes have been successfully compiled and tested in-game.)
