fix(Storage): prevent saving items with empty keys

[hobostay]

Summary

• Add validation to prevent saving storage items with empty keys
• Check if key is empty or contains only whitespace before saving
• Prevents creating invalid storage entries that are difficult to manage

Bug Description

Previously, if a user cleared the key field in the storage editor and clicked save, vConsole would create a storage item with an empty key. These entries are:

• Difficult to select and modify in the UI
• Can cause unexpected behavior when filtering or searching
• Generally inconsistent with proper storage key conventions

Fix

Added validation in onTapSave function that returns early if the key is empty or contains only whitespace, preventing the invalid save operation.

Test Plan

• Open vConsole Storage tab
• Edit an existing storage item
• Clear the key field (or enter only spaces)
• Click the save/done button
• Verify that no empty-key item is created
