fix: update iApp documentation for clarity and structure

- Revised the initial task scheduling description to specify that it takes a few seconds, improving clarity.
- Corrected the link path for the iApp Generator section to ensure accurate navigation.
- Changed the "Start Building" section to "Next Steps" and restructured the content to enhance readability and user engagement, including new links to relevant guides and documentation.
