Fix user having to click 3-4x times before building is deleted (#2195)

## Description:

There is a 5 second cooldown between building deletions (as was proposed
here:
https://github.com/openfrontio/OpenFrontIO/pull/1609#issuecomment-3146188728).

But this cooldown is only checked when in DeleteUnitExecution from
canDeleteUnit in PlayerImpl.
The delete button in RadialMenuElements always gets True back from
canDeleteUnit in GameView.

This results in a user seeing an enabled Delete button after just
deleting another building. And being able to click it, but no deletion
would happen. So they have to click 3-4 times before it 'works'.

Fix: also apply the 5s cooldown when deciding to disable the button. 

In the fix in canDeleteUnit in GameView, added +1 to the current game
tick. So the Delete button is enabled 1 tick before DeleteUnitExecution
would get True back from canDeleteUnit in PlayerImpl. Between seeing and
clicking the button is probably 1 tick anyway, and sometimes also after
clicking it and the execution it takes another tick so this is safe.
Also tested the other way around: after deletion the button should
immediately not be visible, while it can take 2 ticks before GameView
gets lastDeleteUnitTick back from PlayerImpl. But since the Radial menu
is closed after clicking the button, i couldn't open it fast enough
again to still see the button enabled (ie. it was always already neatly
disabled). And if someone with an auto-clicker were to be able to click
it still, their attempt would still be blocked by the cooldown check in
DeleteUnitExecution.
