Release 1.0.3: Use app token in release workflow

[AevumDecessus]

Summary

Fixes prod image workflow not triggering on release events by using fragforce-automation app token instead of GITHUB_TOKEN.

Why

Events triggered by GITHUB_TOKEN do not create new workflow runs to prevent recursive workflows. This is why the prod-image workflow never triggered when releases were created - the release event was created by GITHUB_TOKEN.

Changes

• Release workflow now generates a token from the fragforce-automation app
• Uses app token for gh release create command
• Release events created with app token will now trigger other workflows

Test plan

• Merge to dev and verify CI passes
• Create PR to main
• Merge to main and verify v1.0.3 release creates automatically
• Verify prod image workflow triggers via release: published event (not manual tag push)
