Life events, This Day in History, and spoiler filtering

Life events system - track births, deaths, publications, awards, battles, and more across all entity types. Events appear in a new "History" section on entity detail pages with rich cross-reference links.

This Day in History - a new public page at /this-day shows which literary events happened on today's date. A homepage widget highlights today's events when available. Over 170 book publication dates have been backfilled from Wikidata.

Spoiler filtering for life events - events tied to books you haven't read are hidden behind spoiler guards, matching the existing character spoiler system.

This Day page redesign - event cards now show entity images, dot-divided metadata, and grouped sections by entity type.

Award subtypes - awards now support specific prizes (Hugo, Nebula, etc.) with won/nominated distinctions.
