Keyoapp: fix genres, add type/status filters, exclude novels

[JochemKuipers]

Genres are rendered from an inline initializeDropdownMenu({ type: "genre", items: [...] }) script payload rather than the old #series_tags_page markup, so parseGenres() always returned empty and the filter sheet only ever showed the "Press 'Reset'" placeholder. Parse the script payload, keeping a DOM fallback in case the shape changes.

The same payload carries the type and status dropdowns, so expose those as filter groups, send them as query params, and narrow the results client-side on each entry's data-type and data-status attributes. Fetching now runs off the main thread and guards against overlapping requests when the filter sheet is reopened.

Genre matching was also silently dropping hits across the theme: card tags are frequently padded (e.g. [" Fantasy", "Action "]), and the client-side compare used equals(ignoreCase = true), which tolerates case but not surrounding whitespace. Tags are trimmed before comparing in the theme and in TimelessToons' overridden searchMangaParse.

Most Keyoapp sites return every entry and filter client-side, so multi-select checkboxes are correct there. ArtLapsa and RitharScans filter server-side via single-value controls (a Livewire <select> and mutually-exclusive genre chips), so selecting more than one value sent a repeated query param of which the server keeps only the last — e.g. ?type=manhwa&type=manhua returned only manhua, and manhwa results disappeared. Those sources now use a shared SelectFilter / singleSelectFilterList() path that offers single-choice dropdowns instead.

Novels leaked into every listing. Matching on :not([data-type=novel]) only worked on pages that emit that attribute, so detection also checks the badge text and a "(Novel)" or "[ Novel ]" title marker, and is applied to popular, latest and search theme-wide. Sources can disable it via excludeNovels or adapt it by overriding isNovel(). ArtLapsa also strips Novel from its Type dropdown and derives hasNextPage from the pre-filter entry count so novel exclusion cannot truncate pagination.

Asmotoon drops its now-redundant selector overrides. ArtLapsa, RitharScans and TimelessToons override searchMangaParse, so they apply the novel filter explicitly. ArtLapsa also parses its Livewire <select> options instead of the script payload.
