[frontend] packages/shared: generated ABIs + per-chain addresses + shared TypeScript types

[ozpool]

Context

Shared types package. Consumed by apps/web + apps/keeper. ABIs auto-generated from Foundry out/ — never hand-maintained.

Ref: PRISM_PRD_v1.0.html §Day 1.

Scope

In scope:

• packages/shared/src/abi.ts (generated)
• packages/shared/src/addresses.ts
• packages/shared/src/types.ts

Out of scope:

• Runtime validation (Zod lives in app-layer)

Acceptance Criteria

• Both apps type-check against shared
• All tx states rendered (idle/pending/success/error/wrong-network)
• wagmi v2 + viem v2 (not ethers)
• ABIs from packages/shared (never hand-maintained)
• Keyboard navigable; semantic HTML; WCAG AA contrast
• Responsive at 320 / 768 / 1280
• pnpm typecheck && pnpm lint && pnpm test pass
