gamer147 869727cc06 feat(pack-draw): per-class card pools for rotation-starter packs
Add a nullable ClassId axis to PackDrawCardWeightEntry. Null means the
row applies to any draw (the existing behavior for non-RS packs); 1..8
restricts the row to a specific class draw on a RotationStarterCardPack.
Slot rates are class-invariant (verified against per-klan captures), so
PackDrawSlotRateEntry is unchanged.

PackOpenService.Draw now takes an optional classId parameter. With a
class supplied, the card pool is filtered to (ClassId == classId ||
ClassId == null); without one, class-tagged rows are excluded so a
mistaken non-RS call against a mixed table can't leak class-specific
cards.

PackController.Open lifts the 501 guard on RotationStarterCardPack and
plumbs class_id through. Class_id is now required (and validated 1..8)
for RS packs and rejected as 400 BadRequest on non-RS packs. The skin
overload (target_card_id) remains 501 — out of scope for this work.

Seed JSON regenerated end-to-end: 32 RS packs now carry 30,160 class-
tagged weight rows; 247 non-RS packs keep their existing ~87k null-class
rows. Slot rate fix from the upstream extractor change replaces the
~99.99% conditional-rate sums on 97xxx/93xxx packs with the page's
authoritative 1.5/6/25/67.5 distribution.

Migration AddPackDrawCardWeightClassId. End-to-end bootstrap verified
against fresh Postgres; pack 93025 reads back exactly 122/119/120/120/
120/121/118/119 weights for classes 1-8.

Tests: 3 new PackOpenServiceTests (class filter happy path, disjoint
pools, defensive null-class isolation); existing class_id-on-non-RS
controller test updated 501 → 400 BadRequest; one stub-importer test
corrected to match extractor-authored gacha_detail.
