fix(training-agent): wire seed.creative_format on /sales tenant

[bokelley]

Summary

pagination_integrity_creative_formats is a universal storyboard gated on list_creative_formats. The tool catalog advertises list_creative_formats on sales, creative, and creative-builder (the SDK auto-registers it whenever a tenant claims a creative archetype), but buildSalesComplyConfig only registered the seed adapters relevant to the sales-track storyboards (product, pricing_option, media_buy, creative). The creative_format slot was missing.

Result: seed_creative_format calls on /sales/mcp hit the SDK dispatcher's if (!store.seedCreativeFormat) return UNKNOWN_SCENARIO branch and returned success: false before the v5 handler's LOCAL_SCENARIOS pre-handler could service them. The seed_format_1 storyboard step graded "Expected true, got false" and downstream pagination steps skipped.

seed: {
  ...
  creative_format: cast(seedAdapter('seed_creative_format')),
},

Floor lift on /sales:

Tenant	Old (post-#4061)	New	Delta
/sales	64 / 248	65 / 252	+1 / +4

Other tenants flat — /creative and /creative-builder already wire the adapter via buildCreativeComplyConfig, and the rest don't claim list_creative_formats.

Test plan

• Local matrix run — all six tenants pass new floors
• CI matrix run on PR
• pagination_integrity_creative_formats storyboard now passes 5P/0F on /sales
