Subject: Refactor BobinkClient and clean up comments

- Format BobinkAuth.cpp to match GNU style used elsewhere
- Replace brittle error name array with QMetaEnum in BobinkClient
- Move QOpcUaPkiConfiguration include from header to .cpp
- Replace m_discoveryInterval member with file-scope constant
- Add doc comments to SecurityMode and SecurityPolicy enums
- Comment endpoint selection strategy in handleEndpointsReceived
- Add missing QML ids to connectionPage and serverListView
