feat(editor): add WRPR (Reputation Reward tier) — 109th open format

Novel replacement for the implicit reputation-tier rules
vanilla WoW encoded across multiple SQL tables
(npc_vendor with reqstanding columns, item_template
faction gates, quest_template ReqMinRepFaction). Each
WRPR entry binds one (factionId, minStanding) tier to
its rewards: a vendor discount percentage, two variable-
length arrays of unlocked content (item IDs + recipe
IDs), and tabard + mount unlock boolean flags.

First catalog with TWO variable-length payload arrays
per entry (unlockedItemIds + unlockedRecipeIds) —
previous variable-length formats used a single array
(WCMR waypoints, WCMG members, WPTT spellIdsByRank,
WBAB rank-chain pointers). The two-array shape is
serialized as count1 + ids1[] + count2 + ids2[] for
easy reader-side validation.

Three preset emitters: makeArgentCrusade (4 tiers
Friendly/Honored/Revered/Exalted with progressive items
+ recipes plus Argent Charger mount at Exalted),
makeKaluak (4 fishing-themed tiers with cooking recipe
unlocks plus Pygmy Suit cosmetic at Exalted),
makeAccordTabard (3 tiers showcasing both grantsTabard
and grantsMount flags via Wyrmrest Accord's iconic
Reins of the Red Drake mount).

Validator's most novel checks combine relational and
domain logic: (factionId, minStanding) tuple uniqueness
prevents ambiguous active-tier lookup, AND per-faction
monotonic discount progression — sorts each faction's
tiers by standing and verifies discountPct is non-
decreasing. A higher reputation tier giving a worse
vendor discount would be a content authoring bug.

findActiveTierFor() helper picks the highest-standing
tier the player meets — used by the vendor UI to
compute the active discount without scanning the
catalog.

Format count 108 -> 109. CLI flag count 1184 -> 1189.
