Enhance Infinity Manager Figure Creator Dialog (#17529)

## Summary
This will enhance and add filters for the Figure Creator dialog of
Infinity manager, adding selectable filters for the character dropdown
and displays the series number after the figure/power disc.

## Changes
- Added filter buttons for Disney Infinity 1.0, 2.0, 3.0, and "All"
- Character names now display series information (e.g., "Buzz Lightyear
(1.0)")
- Dynamic dropdown population based on selected filter
- Maintains all existing functionality and slot validation

## Benefits
- Easier character discovery in large character lists
- Better organization by game series
