chore(server): renumber v2 migrations 038-046 to 041-049 after main's 038-040

Main released ProjectionThreadsPinOrderKey (038),
ProjectionProjectsDefaultThreadEnvMode (039) and
ProjectionProjectFaviconPath (040), so the branch-private v2 stack shifts
up by three. Registry ids were already 41-49; this renames the files and
identifiers to match and updates the ledger expectations and through-id
boundaries in the migration tests (released boundary 37 -> 40).
