Prod's /pack/get_gacha_point_rewards offers leader cards from packs
where the leader sits in a non-Legendary tier — UCL pack 16015 has
Kyoka (711531010, Runecraft) and Miyako (711331010, Dragoncraft) as
Gold-tier rows with is_leader=1 in the drawrates. The old filter
(Tier == Legendary && !IsAltArt) excluded them, so the in-game
exchange UI was empty despite the banner advertising leader-card draw
rates.
Fix: filter on (Tier == Legendary || IsLeader) && !IsAltArt. Captures
every legendary plus any leader card regardless of page tier. Verified
against the captured 16015 response in
traffic_prod_all_gacha_exchange.ndjson (28 entries: 26 legendaries +
2 Gold-tier leaders).
Across the seeded data this surfaces 6 additional cards: 3 Bronze-tier
leaders + 3 Gold-tier leaders. The 68 Legendary-tier and 81 Special-
tier leaders were already included.
Renames legendaryCardIds -> exchangeableCardIds for clarity.
Regression test seeds a Gold-tier IsLeader=true card with a Skin row
and asserts the exchange catalog returns it with the Skin reward
entry.

Bootstrap Program.cs now calls PackDrawTableImporter after PackImporter.
Delete DbCardPoolProvider, ICardPoolProvider, and the DbCardPoolProvider
tests — the new IPackDrawTableRepository covers what GachaPointService
needed (legendary-tier card_ids per pack) and PackOpenService takes the
draw table directly.
GachaPointService now resolves the legendary catalog from
PackDrawTable.CardWeights filtered by Tier==Legendary, instead of
ICardPoolProvider.GetPool then a rarity filter. Same end set, no DB pool
walk.
Test fallout: tests that fabricate custom card sets for gacha-point
tests now call factory.SeedPackDrawTableFromSetAsync(packId, setId)
to install a matching legendary-tier stub. Full suite: 647/647 green.

Implements GachaPointService.TryExchangeAsync: validates pack
exchangeability, balance >= threshold, card in catalog, not already
received; debits balance, marks received, grants the card through
RewardGrantService (cascade handles cosmetics). Re-adds the
RewardGrantService injection that was removed in the Task 3 fix-up
(matches the "inject when you call" convention).
Card grant produces the wire-shape reward_list directly via the
cosmetic cascade — the catalog's reward_list remains the display-only
shape for /pack/get_gacha_point_rewards.
