feat(explorer): clarify transaction type and address flow

[moscowchill]

Summary

• Add a neutral transaction-type pill and a responsive From-to-To flow on transaction details.
• Preserve full address links and copy values, receipt status, exact fee display, and existing address-page IN/OUT labels.
• Keep factory-call recipients distinct from child contracts and represent unavailable metadata conservatively.

Validation

• 631 Jest tests across 48 suites passed.
• Lint: no errors; 14 existing warnings. TypeScript and API-doc drift checks passed.
• Production build passed with the unrelated hosted dApp prebuild skipped locally.
• 31 production-browser checks passed, including 14 new transaction-flow cases and 17 existing explorer UI regressions.
• Phone and desktop, light and dark screenshots visually reviewed using synthetic fixtures.
• Independent source review: no blocking findings; 22 focused tests independently passed.
• Prettier passed for new files, tests, and fixture changes. The existing transaction renderer has baseline formatting drift; unrelated formatting was preserved.

Risks and scope

• Presentation-only changes. No backend, network, wallet, balance, or signing behavior changed.
• Transaction type remains independent from execution status. Missing or inconclusive metadata uses a neutral label.
• Pending transactions retain their existing dedicated page.
• Production deployment is separate from this integration PR.
