fix: resolve all TypeScript errors in WAProto and test files

- Changed WAProto.proto syntax from proto3 to proto2 to support required fields
- Regenerated WAProto static files (index.d.ts, index.js) with correct proto2 syntax
- Fixed type annotations in test files (circuit-breaker, sync-action-utils, trace-context)
- Fixed Mock type errors in baileys-event-stream and cache-utils tests
- Fixed LID mapping test expectations to match array type
- All 78 TypeScript errors resolved, 0 remaining
