Add subtype breakdown counter for card selection (#6923)

* Add subtype breakdown counter for card selection

  Display a categorized count of creature subtypes (and other card type
  subtypes) when multiple cards are selected. The breakdown appears above
  the total selection counter in the bottom-right corner.

  Subtypes are grouped by main card type and sorted by frequency, with
  the most common subtypes positioned adjacent to the total count for
  quick reference. The feature can be toggled via a new checkbox in
  Settings > User Interface.

* Alignment fix

* Computation logic moved to helper funtction in separate file

* Rename SubtypeCounter to SubtypeTally

* Fix subtype tally alignment by using grid layout instead of character padding

* Rename count to tally in the subtype breakdown feature

* partial rename

* list position fixed

* Clean up code and documentation

* Rename subtypeCountLabelStyle to subtypeTallyLabelStyle and fix include ordering

* Fix include path for selection_subtype_tally.h after file relocation

* fixed count to tally rename inconsistencies
