fix(dashboard): preselect the saved type/kind in the edit-target form

The edit-target dialog set `value` on the <select> but the <option>s had no
`selected` attribute, so Dioxus rendered the first option (Web Application)
regardless of the target's real type. Editing and saving a PLC/SPS (or any
non-web) target silently rewrote its type to web_app.

Mark the matching option `selected` (type + artifact-kind selects) so the form
opens on the target's actual values.
