Add run dashboard and encounter tracking interface

Run list at /runs shows all runs with status badges. Run dashboard at
/runs/:id displays stats, active team, graveyard, and rule badges.
Encounter tracking at /runs/:runId/encounters shows route list with
status indicators, progress bar, filters, and a modal for logging or
editing encounters with pokemon picker.
