Add Pokemon detail card with tabbed encounter/evolution views

Pokemon edit modal now shows three tabs (Details, Evolutions, Encounters)
instead of a single long form. Evolution chain entries are clickable to
open the EvolutionFormModal for direct editing. Encounter locations link
to admin route detail pages. Create mode shows only the form (no tabs).

Backend adds GET /pokemon/{id}/encounter-locations (grouped by game) and
GET /pokemon/{id}/evolution-chain (BFS family discovery). Extracts
formatEvolutionMethod to shared utility.

-## Backend support
-- Encounters by pokemon: May need a new endpoint or can query route_encounters filtered by pokemon_id
-- Evolution chain: Can reuse existing /pokemon/{id}/evolutions endpoint, but may need a 'full chain' variant that shows the complete family tree (not just direct evolutions from this pokemon)
+## Implementation
+
+### Tabbed modal (edit mode)
+In edit mode, the PokemonFormModal uses three tabs instead of a single scrolling view:
+- **Details** — the form fields (PokeAPI ID, name, types, etc.) with Save/Delete/Cancel footer
+- **Evolutions** — clickable evolution chain rows that open a stacked EvolutionFormModal for direct editing
+- **Encounters** — encounter locations grouped by game, with route names linking to admin route detail pages
+
+In create mode, no tabs are shown (just the form fields).
+
+### Backend endpoints
+- `GET /pokemon/{id}/encounter-locations` — returns encounters grouped by game with route/game names eagerly loaded
+- `GET /pokemon/{id}/evolution-chain` — BFS to find full evolution family, returns all edges with from/to Pokemon
+
+### Frontend
+- New types: `PokemonEncounterLocationItem`, `PokemonEncounterLocation`
+- New API functions: `fetchPokemonEncounterLocations`, `fetchPokemonEvolutionChain`
+- New hooks: `usePokemonEncounterLocations`, `usePokemonEvolutionChain`
+- Extracted `formatEvolutionMethod` to shared `utils/formatEvolution.ts`
 
 ## Notes
 - This helps the admin quickly verify data completeness — 'is this pokemon assigned to the right routes?' and 'are its evolutions set up correctly?'
