Make room panel tabs interactable when you own it but can't make it.

[Spatulade]

Aim is to change room logic so that:

• if room is owned but cannot make it (yet or at all), the room icon can be interacted with (but you cannot make it, only left-click to see how many you have and capacity, or right click to zoom to one).

This initial step lays some groundwork but needs checking and refining.

To do:

• like with the traps, have this state be enabled but only partially interactable - don't let the player make the room, but let them see info and zoom.
• replace cost with the "cannot make" manufacture symbol.
• Add tooltip relating to this.
