- Add `= None` default to `Optional[str]` field in CardOfTheWeekResponse
(Pydantic v1 convention: Optional fields should have explicit None default)
- Remove unused `_PACK_COUNTER` dead variable from test module
- Remove unused `cardset` parameter from `_make_pack_type` helper and
update all 6 call sites

Exposes the highest-rated card from the past 7 days (configurable via
?days=) as a Discord-embed-ready payload. AI teams are excluded by
default (?include_ai=true lifts the filter). Deterministic tiebreak:
rating desc, pack open_time desc, card id desc.
Roadmap: Phase 2.6c — lowest-friction entry into the automated content
pipeline. Single-call response includes player name, team, rarity,
rating, card image URL, and cardset name.
