Add task deletion with confirmation modal

[Copilot]

Implements task deletion functionality allowing users to remove tasks from the database. Includes a custom confirmation modal with proper error handling and ownership verification.

Changes

Backend

• Added deleteTaskById in task DAO using findOneAndDelete with user ownership check
• Added deleteTask controller handling DELETE requests with 404/500 error responses
• Registered DELETE route at /:taskId in task router

Frontend

• Delete button appears on task hover with trash icon
• Custom confirmation modal replaces native confirm() for consistent styling
• performDeleteTask makes API call and updates local state on success
• Error messages displayed on failed deletion via existing toast pattern

Error Handling

• Try-catch wrapping API call with user feedback on network/server failures
• Ownership verification on backend prevents unauthorized deletion
• Validates both HTTP status and response success field

Example Usage

// Frontend: User clicks delete button, sees confirmation modal
<button onClick={(e) => deleteTask(task._id, e)}>
  <Trash size={20} weight="bold" />
</button>

// Backend: Secure deletion with authorization
const task = await Task.findOneAndDelete({ _id: taskId, userId });
