Improve BlueAPI logging to add plans registered and version of repositories in scratch area

[oliwenmandiamond]

When using BlueAPI, the typical logging you would see at startup is as follows:

2026-03-26 10:45:14,619     INFO numexpr.utils NumExpr defaulting to 16 threads.
2026-03-26 10:45:16,676     INFO uvicorn.error Started server process [1]
2026-03-26 10:45:16,691     INFO uvicorn.error Waiting for application startup.
2026-03-26 10:45:20,108     INFO Dodal Setting global path provider to <blueapi.utils.path_provider.StartDocumentPathProvider object at 0x7f5e6cdf02d0> (previously None)

It would vastly improve the user experience when trying to deploy this to know exactly what version/branch of the repositories included are that BlueAPI picked up and to also know exactly what plans are included, same as the devices that were included.

e.g

INFO Using sm-bluesky version XXX (on branch YYY)
INFO Using dodal version XXX (on branch YYY)

and

INFO blueapi.core.context Including plans from dodal.plan_stubs
DEBUG Registered plan "move"
DEBUG Registered plan "move_relative"
