fix(gacha-points): include IsLeader cards regardless of draw tier

Browse Source 
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.
