fix: preserve user-requested platform as fallback in formatProjectCreated

The old code used `project.platform || platform` where `platform` was
the user's CLI argument. The migration lost this fallback by hardcoding
"unknown". Add `requestedPlatform` field to `ProjectCreatedResult` and
use it as fallback when the API response has no platform set.
