[Web BUG] Personal Plan share functionality is broken

Describe the Bug The sharing options for the Personal Plan are malfunctioning.

It defaults immediately to composing an email instead of opening a share menu (where applicable).

The Personal Plan file/image is not attached to the share action.

To Reproduce Steps to reproduce the behavior:

Go to the 'Personal Plan' section.

Click on the 'Share' button.

Observe that it forces an email draft and no file is attached.

Expected Behavior The button should trigger the native web share API (or allow app selection) and include the plan file as an attachment.

Start at the Personal Plan section's Share button implementation and trace the web-specific sharing path. Reproduce the issue in a browser, then verify that the share action opens the native web share or app-selection flow and includes the plan file as an attachment.
