Add software compilation merge to Blazor and Uno admin apps

Lets admins merge duplicate SoftwareCompilation entries: a new
POST /software-compilations/{id}/merge endpoint re-parents releases,
covers, junction rows (with dedup/self-loop guards), and predecessor
references onto the target before deleting the sources. Wired into
both the Blazor MudBlazor admin page and the Uno admin page, each
with a search-based target/source picker, plus full localization.
