kyc.screen Sumsub onMessage callback still uses any

[marassteiner]

Context

Follow-up from #1271

PR #1271 touches src/screens/kyc.screen.tsx. The Sumsub onMessage callback still takes payload: any. The type was already there; this PR did not introduce it. CONTRIBUTING.md still wants touched files reported, so this is tracked separately rather than blocking the pending-recommendation hint.

Evidence

• src/screens/kyc.screen.tsx:1843 — onMessage={(type: string, payload: any) => {

Suggested direction

Replace any with a narrow Sumsub payload type (or unknown plus a type guard) before reading payload.reviewResult.

Acceptance

• No any on the Sumsub onMessage callback
• The RED/FINAL and GREEN branches still type-check
