docs: fix broken refs and rewrite stale handler docs

[chubes4]

Summary

• eventbrite/ics/prekindle handler docs: Rewritten as deprecation notices. The standalone handlers (Handlers/Eventbrite/, Handlers/IcsCalendar/, Handlers/Prekindle/) were removed and consolidated into WebScraper extractors (EventbriteExtractor, IcsExtractor, PrekindleExtractor). Old docs described deleted classes and registration code — now they point to the replacement extractors with migration guidance.
• pagination-system.md: Calendar_Query.php no longer exists. Updated all references to PageBoundary.php and CalendarAbilities.php. Updated code examples, import paths, and debug snippets.
• calendar-block.md: Fixed .js → .ts file extensions, removed non-existent modules/state.js (functionality is in modules/filter-state.ts), added missing modules (day-loader.ts, geo-sync.ts, lazy-render.ts), fixed Template_Loader path from inc/Core/ to inc/Blocks/Calendar/.
• universal-web-scraper-handler.md: Added all 35 extractors to the Extractors directory section (was only 15) and expanded Supported Sources from 13 to 30 entries.

Test plan

• Verify no doc references files/classes that don't exist on disk
• Verify deprecation notices correctly point to replacement extractors
• Verify code examples use correct class names and namespaces
