Adds four Tier 3 (medium-priority) test cases to the existing refractor test
suite. All tests use SQLite in-memory databases and run without a PostgreSQL
connection.
T3-1 (test_refractor_track_api.py): Two tests verifying that
GET /api/v2/refractor/tracks?card_type= returns 200 with count=0 for both
an unrecognised card_type value ('foo') and an empty string, rather than
a 4xx/5xx. A full SQLite-backed TestClient is added to the track API test
module for these cases.
T3-6 (test_refractor_state_api.py): Verifies that
GET /api/v2/refractor/cards/{card_id} returns last_evaluated_at: null (not
a crash or missing key) when the RefractorCardState was initialised but
never evaluated. Adds the SQLite test infrastructure (models, fixtures,
helper factories, TestClient) to the state API test module.
T3-7 (test_refractor_evaluator.py): Two tests covering fully_evolved/tier
mismatch correction. When the database has fully_evolved=True but
current_tier=3 (corruption), evaluate_card must re-derive fully_evolved
from the freshly-computed tier (False for tier 3, True for tier 4).
T3-8 (test_refractor_evaluator.py): Two tests confirming per-team stat
isolation. A player with BattingSeasonStats on two different teams must
have each team's RefractorCardState reflect only that team's stats — not
a combined total. Covers both same-season and multi-season scenarios.

Complete rename of the card progression system from "Evolution" to
"Refractor" across all code, routes, models, services, seeds, and tests.
- Route prefix: /api/v2/evolution → /api/v2/refractor
- Model classes: EvolutionTrack → RefractorTrack, etc.
- 12 files renamed, 8 files content-edited
- New migration to rename DB tables
- 117 tests pass, no logic changes
