Allow rack elevation backdrops to extend sideways to wrap long device names

[AliMickey]

If a device name is long (~40 chars) it will overlay on the rack elevation image making it hard to read.

Example:

I understand simply increasing the width of the rack model isnt desirable, as it would cause issues with the device type images.

An alternative maybe is to left align the device name text, so that it does not overflow to the left side, and simply extend the backdrop on the right side to cover the device name.

Example:

Might not be the best solution, but in my opinion better than the current implementation.
