Source code for GUIBRUSHR.GUI.Input_Output_Panels.Input_Panels.TabPanels.FrameDBInteractions.FrameReload

"""
FrameReload module: maintenance buttons for the DB and Data Interactions tab.

Provides two on-demand actions:

- Reload Targets: re-scan the targets folder and refresh the Target dropdown in
  every panel.
- Reload Opacities: re-scan the petitRADTRANS opacity folders and rebuild the
  molecule/isotope/opacity dropdowns in the retrieval Parameters panel and the
  Forward Model panel.

Both delegate to InputPanel so the cascade/rebuild logic lives in a single place.
