Auto-select boss team variant based on starter choice

When a run has a starter Pokemon, automatically match its species name
against boss battle condition labels (e.g., "charmander" matches "Chose
Charmander"). If exactly one variant matches, pre-select it and hide the
pill selector. Falls back to showing pills when no match is found.

Fixes starter lookup to use game routes data (which has encounterMethods
populated) instead of the run detail route (which defaults to empty).
