chore(enrichment): peg hosted credit cost to each provider's lowest paid plan

Align *_CREDIT_USD to the entry tier Sim will provision:
- Datagma: Regular $49/3,000 emails → $0.0163 (was Popular $0.0132)
- LeadMagic: Basic $49/2,000 → $0.0245 (was Growth $0.0104)

Icypeas (Basic $0.019), Enrow (Starter $0.012), and Dropcontact (Starter
~$0.17) already reflect their lowest plan. Tests derive from the constants,
so values stay consistent.
