[Unknown Mod][Locations] Add a "Hero" button in the creature dwelling rally window

[LeHerosInconnu]

A "Hero" button is added (always available) in the creature dwelling rally window, between the "YES" and the "NO" buttons.

When all slots of the hero's army are occupied and the hero wants to recruit créatures in a creature dwelling on the adventure map, the displayed window allows to go directly to the hero's screen with the "Hero" button to reorganize the troops, and the "YES" button is grayed out.

If the "Game: Hero and Captain have extended inventory for creatures" option is enabled (#2995), the "Hero" button is available, and the "YES" button is not grayed out.
Creatures are transferred directly to the extended inventory for creatures if the player presses the "YES" button.

Old windows as a reference for now:

This is not an option.
This can be implemented directly in fheroes2.
