Fix: Prevent Unsaved Data Loss During File Management

Related Issue

• Closes Active Workspace Wiped When Deleting Unrelated Files #80

Description of Changes

• Modified the deletion handler within the IonAlert in Files.tsx.
• Previously, deleting any file triggered loadDefault(), which erased the active spreadsheet.
• Added a conditional wrapper if (currentKey === props.file) around the loadDefault() function.

Impact

• Data Protection: Users can now safely delete old or unwanted files from their file manager while actively working on a different invoice without fear of their current screen being wiped.
• Workflow Integrity: The workspace now correctly persists unless the user specifically deletes the exact file they are currently viewing.
