Ensure all model proxy caches are flushed before access

Browse Source

This fixes a defect where station detail changes are not saved.

The Qt sort and filter proxy models utilize an item cache that must be
flushed by  callig submit() before  accessing the underlying  model if
the proxy model has been used for updates.

Also  separated  the   item  model  candidate  key   filter  from  the
implementation  internals of  the foreign  key item  delegate so  that
candidate key filtered models can be used directly as view models.

Make the insert new station details band combo box use a candidate key
filtered item model to avoid constraint violations. Constraint is zero
or one station records per band.
