load·in 1.5.2: slot numbers that hold, and real-file trust

This release is about trusting the app with real show files.

Imported channels now keep their original console slot numbers. Deleting an imported channel can leave its slot reserved as a spare instead of renumbering the rest of the patch.

Allen & Heath dLive: verified strip edits (filter, EQ, dynamics) write back to version 13 archives on the patch-in-place path. Behringer X-Air: exports keep stereo links and pans exactly as the desk file carries them — only changes made in the app are written. DiGiCo SD: re-exporting an imported session with no edits returns the file unchanged. Avid VENUE S6L: the export preview now states clearly when a high-pass filter frequency can't be written.

Swedish joined the in-app languages, bringing the total to eleven.
