fix(downloads): compact finalization statuses

Normalize German and English finalization producer labels before they reach package and item status cells. Derive percentages from valid fractions, clamp them to the visible 0-100 range, and reduce malformed fractions or zero totals to the phase name.

Preserve legacy percentage labels while preventing finalization lines ending in archive names from being classified as bare extraction archives. Cover current and legacy forms, both languages, package and item rendering, localization, and invalid numeric input.
