Refactor detail tabs; add series & Playnite options

Split DetailView into focused tab components (Overview, Cast, Seasons, Tracks, Series) and moved related UI/logic into src/components/details/tabs/*. DetailView now composes these tabs and accepts allMedia for series lookups; MediaDetailRoute forwards allMedia.

Support for series was added across the stack: API types and converters now include series, Media type gained series and cleanname fields, and BrowseView now lists/filters by series (label updated to 'Series' and dropdown default changed to '--- Alle ---').

Playnite importer: introduced PlayniteImportOptions (limit, nameFilter), added UI inputs to ImporterView, increased existing media fetch limit, added name filtering, import limiting, deduplication and improved cleanname-based matching/logging. Adjusted progress/total handling to account for deduped items.
