chore: update viem to 2.43.2

[devin-ai-integration]

Description

Updates the viem dependency from 2.37.9 to 2.43.2 across the entire monorepo. This update includes the Moonbeam RPC fix from wevm/viem#4181, which updates Moonbeam and Moonriver chains to use their official RPC URLs instead of BlastAPI endpoints.

Packages updated:

• cdn, experimental, siwe, siwx: Direct dependency updated to 2.43.2
• appkit, appkit-utils, common, controllers: Peer dependency minimum version updated to >=2.43.2
• apps/browser-extension, apps/demo, apps/laboratory: Direct dependency updated to 2.43.2
• All 16 example apps: Direct dependency updated to 2.43.2

The peer dependency minimum versions and all app/example dependencies were updated to ensure consistent viem types across the monorepo and avoid TypeScript type incompatibilities between viem 2.37.9 and 2.43.2.

Type of change

• Chore (non-breaking change that addresses non-functional tasks, maintenance, or code quality improvements)
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
