[Bug]: Shop input fully blocked after listing a vehicle for sale ( double-click / buy do nothing) tested in solo run too

[andresok50]

Description

After listing a vehicle for sale via ESC → Vehicles → Sell, the shop becomes completely unresponsive. Clicking any vehicle in the shop grid, double-clicking, pressing PERSONALIZAR, or BUY produces no response. The shop renders correctly but all input is dead. The game must be restarted to recover.

Expected: Shop works normally after listing — vehicles open on double-click, PERSONALIZAR opens the config screen.

Actual: All shop input is silently swallowed. Confirmed via debug log that ShopConfigScreen.setStoreItem is never called after the sell flow.

Root cause (from log analysis with DEBUG=true):

Two issues identified:

1. The engine sets SellItemDialog.visible = true before calling g_gui:showDialog(). The mod intercepts and blocks that call without clearing the flag, leaving the dialog in a visible=true / isOpen=nil phantom state that partially blocks GUI input.

2. SellVehicleDialog does not call g_gui:changeScreen(nil) on confirm/cancel. The vanilla SellItemDialog did this automatically. Without it, InGameMenu stays as currentGui after the dialog closes and captures all shop clicks.

Log evidence:

Steps to Reproduce

1. Load any save (solo mode).
2. Open ESC → Vehicles, select any owned vehicle.
3. Click Sell — confirm the listing in the UsedPlus SellVehicleDialog.
4. Close the ESC menu. Open the shop (P key).
5. Navigate to any vehicle category (e.g. Small Tractors).
6. Double-click any vehicle, or press PERSONALIZAR.
7. Nothing happens — all shop input is blocked until game restart.
