feat(export): direct download of the complete archive from the Exportera tab (#1632)

The full-archive ZIP endpoint (SIE + reports + all documents) has existed
since the settings/backup page, but lost its UI when that page became a
redirect: the BackupDownloadForm component was orphaned and the download
was API-only. Resurface it the way the export tab already works: a
"Komplett arkiv" ImportRow (owner/admin only, matching the route's role
gate) opening a small centered dialog like the SIE export next to it,
with scope choice, fiscal-year picker, include-documents toggle, live
size estimate, 413 handling, and a #full-archive deep link.

The orphaned form and its dead settings_backup_download i18n namespace
are deleted; its logic lives on in components/import/FullArchiveDialog.
Over-limit copy now points at the existing cloud sync instead of
promising it "in a later version".
