Add FrontRow to Open Source Apps

[majdukovic]

Hi, would like to add my project to the Open Source Apps section.

FrontRow is an MIT licensed React Native concert ticketing app I built specifically as a QA automation training surface. The thing that makes it different from other RN apps in the list is that it's purpose built for testing practice rather than as a product or UI demo. It has a deep QA Debug Menu (force error modes, time travel, deterministic IAP outcomes), a cross platform testID contract that works across Maestro, Appium, Espresso and XCUITest from the same registry, 30 Maestro flows, and a couple of bridged Swift and Kotlin native screens.

Repo: https://github.com/majdukovic/frontrow

I checked the guidelines:

• Searched the list for duplicates, no existing entry for this project
• One PR, one suggestion
• Format matches the existing convention * [PACKAGE](LINK) - DESCRIPTION.
• Description ends with a period
• No trailing whitespace
• Project is tested and documented, CI runs Jest, Prettier and ESLint plus the Maestro suite, docs in /docs

Happy to revise the wording or move the entry if you'd prefer.
