Underground Ruins: fix hidden door puzzle flow

[jotacarma90]

#Description

• Initialize() now handles load-time door state correctly: if the puzzle is already solved, the door opens immediately; otherwise the puzzle is re-initialized and the door is reset closed.
• GenerateSolution() is deterministic and always requires all 8 cores (1,1,1,1,1,1,1,1), removing random/unclear puzzle states.
• OnSwitchUse() is the solve path: it validates the item stands, sets solved state, and opens the door only when the full correct setup is present.
• Direct door bypass is blocked with a Door.Interact Harmony prefix (PuzzleDoorInteractPatch), allowing interaction only when the puzzle has been solved.
• ResetDoorState() writes ZDOVars.s_state = 0 for unsolved initialization, ensuring closed-door behavior until a valid solve occurs.
• Lever interaction text is explicitly set to include $KEY_Use (Submit Offering), so the interaction prompt is consistently visible.
