Extract helpers into BoardUtils, WisdomBuilder, UISync, PlatformUtils

- BoardUtils: BoardTypeName (removes duplication with DeviceForm)
- WisdomBuilder: TWisdomBuildThread + TWisdomProgressDialog
- UISync: TDeviceFoundSync/TStatusUISync/TDDCSeqSync via callbacks
  (avoids circular dependency, removes TObject casts)
- PlatformUtils: HasOpenGLSpectrumSwitch + CurrentScreenDPI
