refactor: Replace "Platform" with "SmoothSchedule" in licensing section

Updated all references to "Platform" in the licensing documentation to use
"SmoothSchedule" for better branding consistency:

- Changed "Platform Rights" to "SmoothSchedule Rights"
- Changed "Platform Service Rights" to "SmoothSchedule Service Rights"
- Changed "Platform Use" table header to "SmoothSchedule Use"
- Updated all inline references from "Platform" to "SmoothSchedule"

This makes the licensing terms more specific and branded while maintaining
the same legal structure and protections.
