feat(explorer): label propAMM swaps

[decofe]

Summary

• decode propAMM TradeExecuted logs into token-aware swap summaries
• hide the matching settlement transfers from transaction descriptions
• keep Earn summaries primary while showing an embedded propAMM swap immediately after them

Before / after

Transaction	Before	After
Standalone propAMM swap	Token Transferred 0.01 USDY	propAMM Swap 0.01 USDY for 0.011449 USDC.e
Earn redemption with embedded propAMM swap	Earn exact withdrawal only	Earn exact withdrawal, followed by the nested propAMM swap

Testing

• pnpm --filter explorer check
• pnpm test in apps/explorer (17 files, 128 tests)
• pnpm precommit

The monorepo-wide pnpm check reaches unrelated generated Cloudflare binding errors in apps/contract-verification; the affected Explorer checks pass.
