refactor: reorganize deep linking types and interfaces

Changes:
- Move deep link types from types/ to interfaces/
- Export baseUrlSchema for external use
- Add trailing commas for better git diffs
- Fix type inference for deepLinkSchemas
- Add deepLinks export to interfaces/index.ts
- Remove duplicate SuccessResult interface
- Update import paths in services/deepLinks.ts

This improves code organization by centralizing interface definitions
and fixing type inference issues.
