FEATURE: beacon-based implementation for BPV (#38897)
This commit adds a new parallel page view counting system that uses `fetch` with `keepalive: true` to POST to a dedicated `/srv/pv` endpoint, gated behind the `use_beacon_for_browser_page_views` site setting.                                                                                                                                                                        

Unlike the existing deferred tracking (which piggybacks on AJAX headers), the beacon approach sends page view data directly as a JSON body. Both systems run simultaneously when the setting is enabled to allow comparing counts before fully migrating.

Key details:
                                                                                                                                                                                                                                      
* New middleware endpoint `POST /srv/pv` short-circuits with 204
* Dedicated `ApplicationRequest` counters (`*_beacon`) track beacon page views separately from the existing browser page view counters
* A separate `:beacon_browser_pageview` DiscourseEvent avoids double-firing with the existing `:browser_pageview` event
* On Ember route transitions, `routeDidChange` sends the beacon. For non-Ember pages (e.g. `/pub/*`), `pageview.js` handles it
