Species Search Overhaul
- Replaced the free-text keyboard species search with a visual two-step picker
- First screen: alphabetical letter grid - select a letter to filter species
- Second screen: species list with sprites, sorted alphabetically - select to set the filter
- Only species available in the current game are shown
- Letters with no matching species are dimmed and cannot be selected
- Selected species appears with its sprite on the search filter screen
- Select "-" to clear the species filter back to "any"
