fix(lubimyczytac): restore search results and detail-page metadata

LubimyCzytac.pl restructured its markup, which broke the provider in
four places:

- Search results moved from `authorAllBooks__single` to `book-card--l`,
  so `parse_search_results()` matched nothing and every query returned
  zero results.
- The publisher moved out of the `<dl>` definition list into a
  `span.book__txt` element, so `publisher` was always None.
- The description moved from `div.collapse-content` to
  `#book-description`, so `_parse_description()` silently fell back to
  the truncated `og:description` meta tag.
- The book page now emits an `Organization` ld+json block before the
  `Book` one, and `_parse_from_summary()` only read the first block, so
  `publishedDate` was always None.

Verified against live HTML for 9 search queries and 14 book pages:
queries returning matches 0/9 -> 9/9, publisher 0/14 -> 14/14,
publishedDate 0/14 -> 14/14, description 0/14 -> 14/14 (3.1x more text
than the meta-tag fallback across 18 end-to-end results).
