feat: rename/relocate a profile's SQLite logbook (QSOs carried across)

"Choose a dedicated file" points at a fresh/empty file; there was no way to
rename or move an existing logbook WITH its data. RenameLogbook VACUUM INTOs the
active profile's SQLite logbook to a new path, repoints the profile and switches
the live logbook (no restart). Deletes the old file only when it was a dedicated
per-profile file; the shared default logbook.db is left for other profiles.
Errors on a MySQL logbook. UI: "Rename / relocate…" button in the logbook section.
