Blueapi device name is different to actual device name #1700

Related to DiamondLightSource/dodal#2216 and #1697.

Devices in ophyd-async and dodal have device names like so parent-child-x. However, blueapi uses an internal name lookup equivalent of parent.child.x. This causes issues where the device blueapi uses to lookup on the server, run engine documents, and device logging are all different to each other. Blueapi also keeps track of two separate naming conventions, complicating the code where we shouldn't need to.

Blueapi should unify the device name to lookup on the server and should actually use the true name of the device. This will also be helpful if issue #1671 is fixed first because then blueapi will know about all child devices up front.

Acceptance Criteria

• Blueapi device lookup uses the true device name.
