fix(docs): Fix service run commands to include all package files

- Change from 'go run ./cmd/{service}/main.go' to 'go run ./cmd/{service}/*.go'
  - go run with single file doesn't include other files in the package
  - Service implementations are in separate _fx.go files
  - Using wildcard includes all .go files in the package

- Update README.md and SUMMARY.md with correct commands
- Fixes 'undefined: provideXService' errors when running services
