Create a script to populate the development database with realistic test data for manual testing.

## Requirements
- Multiple runs across different games with varied statuses:
  - 2 failed runs (different games, progressed partway)
  - 2 completed runs (different games, most routes visited)
  - 2 active/in-progress runs (different games, early-to-mid progress)
- Each run should have a mix of encounter states:
  - Caught (alive): with nicknames, catch levels
  - Caught (dead): with faint_level, death_cause
  - Fainted (failed to catch)
  - Missed (ran away / KOd)
- Some caught Pokemon should be evolved (current_pokemon_id set via the evolutions table)
- Runs should use varied rule configurations (some with pinwheel clause off, some with hardcore mode, etc.)
- Respects the one-encounter-per-group constraint (only one child route per parent group gets an encounter, unless pinwheel zones apply)

## Implementation
- Add inject_test_data.py to backend/src/app/seeds/
- Follows the same async session pattern as run.py
- Queries DB for real game_ids, route_ids, pokemon_ids, and evolution chains so data is always valid
- Invocable via python -m app.seeds.inject_test_data (standalone entry block)
- Clears existing runs+encounters before injecting (idempotent)
- Prints summary of what was created

## Checklist
- [x] Create inject_test_data.py with test data injection logic
- [x] Wire up as standalone script (python -m app.seeds.inject_test_data)
- [x] Verify it runs cleanly against a seeded database
