docs(wiki): actualize pages for 0.40 and the Simkl / statistics release
Wiki was last updated for 0.39. Covers everything user-facing added since,
in all three wiki languages (en / ru / zh).
New pages: Simkl Import (PIN sign-in, what each section maps to, episode
marks, wishlist fallback), Statistics (period tabs and every block of the
page).
Updated: Search (TVmaze, Kitsu anime + manga, MangaDex, Google Books,
Hardcover, ComicVine and their filters), Item Details (season posters,
episode stills and overviews, mark-next-episode, Kitsu anime tracker,
similar manga row, progress badge), Collections (favourites filter, bulk
add / remove tags, type counts follow subfilters), Import / Export (light
.xcoll refetches from every provider, watched marks in full exports,
{link} and {type} tokens, dates preserved on restore), Mood Grid (tap
zones, cell-label template, sticky picker, cell size stepper, export),
Personalization (three views, statistics first), Settings and Getting
Started (six interface languages), API Keys (keyless sources, Simkl),
Releases (episodes come from the show's own provider), Wishlist, FAQ,
Home and the sidebar.
Also fixed two links that pointed at a non-existent page title.
