#1928: Added Upgrade IDEasy and Update functionalities to the GUI with pro active notifications

[JoelAdbu]

This PR fixes #1928

This PR continues the work started in: #2027

Implemented Changes

1. Created UpgradeController

   • On startup, IDEasy checks whether the installed version is outdated.
   • If so, an indicator is shown near the Logo that opens a dialog and allows running the upgrade command.

2. Created UpdateController

   • After selecting both a project and a workspace, an update check is performed.
   • If an update is available, an indicator is shown near the project ComboBox, opening a dialog that allows running the update command.

3. Controller / architecture adjustments

   • Refactored MainController to allow dependency injection.
   • Reduced singleton-based wiring to improve flexibility and testability.

4. Localization

   • Aligned the implementation with #1936.
   • Added/updated English and German texts in messages.properties and messages_de.properties.

5. Tests

   • Added UpgradeUpdateFlowTest as end-to-end GUI integration tests for both update and upgrade flows using the new indicator + dialog pattern.

6. UI refactoring

   • Refactored main-view.fxml so the tool cards are displayed in a grid layout, aligned with the Figma design:
   • https://www.figma.com/design/cEcWlvnNOS5xVE2kQFZe0R/IDEasy?node-id=0-1&p=f&t=0mK55q4GEpGWvnCB-0

7. Tray notification service

   • Added TrayNotificationService to avoid duplicated tray-indicator logic.
   • Used by both UpgradeController and UpdateController to show the clickable tray indicator when an upgrade or update is available.

Testing Instructions

1. GUI testing with overridden configuration

A test configuration class was added: TestGuiConfiguration

This allows overriding the current IDEasy version and update availability via environment variables when launching the GUI.

Example:

IDE_VERSION=2026.02.001;IDE_UPDATE_AVAILABLE=true

Usage:

TestGuiConfiguration.applyConfigOverrides();

Note: This call in App is only for testing and should be removed before merge.

Upgrade flow

1. Start the application.
2. Click the indicator at the top-right of the IDEasy logo.
3. Expected result:
   • A dialog opens.
   • The dialog shows the current and latest IDEasy versions.
   • The Upgrade button executes the upgrade command.

Update flow

1. Select a project.
2. Select a workspace.
3. Click the indicator at the top-right of the project ComboBox.
4. Expected result:
   • A dialog opens.
   • The dialog shows an Update Available status.
   • The Update button executes the update command.

2. Run automated tests

Run the following test class:

UpgradeUpdateFlowTest

This validates both update and upgrade flows
