Fix build matrix condition to properly detect workflow_dispatch trigger

- Added debug output to show event name and inputs

- Fixed empty string check for build_sources input

- Now correctly expands matrix for manual/scheduled runs

- Manual runs without custom input will test all 6 sources (current + 5 PRs)
