Add kmp modules for shareable domain and ui components

[andreia-ferreira]

Towards #3575 ; #3600

In order to share LOI geometry as a QR code containing a GeoJSON, this PR adds a reusable UI component GroundQrCode, intended to be used in at least two places: the LOI job sheet and the end of a data collection flow.

It also introduces a new domain model LoiReport (currently holding the LOI GeoJSON). In a follow-up step, this will be expanded to include the full LOI survey data so it can be downloaded/exported as a PDF.

As a step toward #3416 , the shareable pieces were extracted into KMP modules :core:ui (reusable UI) and :core:domain (pure domain models/logic). More code will be moved incrementally in smaller PRs to keep reviews focused and reduce risk.

Note: The new modules compatibility with iOS was tested in a separate branch (open iosApp in xcode and run the project, it should display a simple qr code element)

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request lays the groundwork for enhanced data sharing capabilities by introducing Kotlin Multiplatform modules for core domain logic and UI components. The primary goal is to enable the generation and display of QR codes containing LOI GeoJSON data, with future plans to support comprehensive LOI survey data export. This architectural change promotes code reusability and prepares the project for multiplatform development.

Highlights

• New Kotlin Multiplatform Modules: Introduced two new Kotlin Multiplatform (KMP) modules: :core:domain for pure domain models and logic, and :core:ui for reusable UI components. These modules are configured for JVM, Android, and iOS targets, enabling code sharing across platforms.
• Shareable LOI Geometry via QR Code: Added a new LoiReport domain model to hold LOI GeoJSON data, facilitating the sharing of LOI geometry as QR codes. This is a foundational step towards expanding LOI survey data export.
• Reusable QR Code UI Component: Implemented a GroundQrCode composable in the :core:ui module, designed to display QR codes from any string payload. This component is intended for use in various parts of the application, such as LOI job sheets and data collection flows.
• Gradle Configuration Updates: Updated Gradle build files across the project to integrate the new KMP modules, migrate SDK and JVM toolchain versions to the libs.versions.toml catalog, and include necessary KMP and Compose Multiplatform plugins and dependencies.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request introduces new Kotlin Multiplatform (KMP) modules, :core:domain and :core:ui, to facilitate code sharing for domain models and UI components. This is a great step towards modularizing the application. The changes also involve migrating build configurations to use the version catalog, which improves dependency management. My review includes several suggestions to align with the repository's style guide, particularly regarding copyright headers and the addition of unit tests for new code. I've also included some recommendations to improve the implementation of the new GroundQrCode composable for better clarity and simplicity.
