✨ Delete tasks

[Friedinger]

This pull request introduces a major refactor to the task details view, improving separation of concerns and user interaction with tasks. The main changes include extracting view logic into a dedicated TaskDetailsViewModel, adding support for deleting tasks both locally and remotely, and enhancing the app bar to support menu actions.

Task deletion and management improvements:

• Added a deleteRemote method to the Task model to support deleting issues from the remote repository, with logging for success or failure.
• Added a deleteTask method to TaskHandler that removes a task locally and remotely, and notifies listeners of changes.

UI and view model refactor:

• Extracted task details logic into a new TaskDetailsViewModel class, moving editing, deletion, and state-changing actions out of the view and into the view model. This improves code organization and maintainability. [1] [2]
• Updated TaskDetailsView to use the new view model, replacing direct logic with calls to view model methods, and moved floating action buttons and menu actions to use the view model. [1] [2] [3]

App bar enhancements:

• Modified NormalAppBar to accept a list of menu items, enabling popup menu actions such as task deletion from the app bar. [1] [2]

Minor updates:

• Cleaned up imports and improved type safety for the backVisible property in NormalAppBar. [1] [2]
• Updated documentation and comments for improved clarity.

Deleting tasks currently fails, but I think that it is a problem on github_flutter's side and not here
