Local adjustments - Fix apply/paste actions with LA

- Fixes LA lost when applying partial profile (fixes #6150)
- Fixes LA behavior when using apply/paste actions: spots are now totally replaced and not anymore merged (fixes #6136 and #6411)
- Fixes a crash in specific situations when saving/copying a partial number of spots
- Partial paste dialog: Fixes Locallab button remaining inconsistent if all the spots are deselected
