SSR control center: auto-purge webhook, dashboard tiles, backend module

Package 1: SsrPurgeService posts to the node /__purge (endpoint+secret in var/vitec-ssr-purge.env, outside git) and logs every attempt to tx_vitec_ssrpurgelog. DataHandler hooks queue per request and flush once: pages with nav-relevant field changes and all tx_news_/tx_vitec_ records purge everything, other page/content edits purge the hosting page path. Gated by the routing flag and the new Site Set switch vitec.ssr.autoPurge. Flipping the SSR switch ON purges everything once. CLI: vitec:ssr-purge, vitec:ssr-health (samples /__health into tx_vitec_ssrhealthlog, 14 days kept, scheduler-ready). Package 2: dashboard widgets vitecSsrStatus (live health, release, switch, last purge) and vitecSsrStats (purge counts, failures, uptime, response time). Package 3: backend module web_vitecssr with manual purge (paths or everything) and both protocols. Tested end to end against the running node (purge single/all 200, health sample logged).
