feat(cache): single-owner caching across nginx, edge and content edits
Rebuild production nginx from the repo (deployment/proxy/*) with a single
Cache-Control owner per route: the app stays the source, nginx only manages
headers, and Cloudflare stores the public API allowlist at the edge.

- deployment/proxy: nginx.conf, mime.types, nginx-cms.conf and the
  blue/green upstream snippet; config backed by scripts/nginx-sync.sh
  (idempotent install + reload, --check/--force).
- nginx serves Cache-Tag headers on the public allowlist (cms-public),
  gamedata, client and camera responses so the edge and purge stay in sync.
- src/lib/edge-cache.ts + tests: coalesced, fire-and-forget edge purges that
  no-op unless Cloudflare is configured; scripts/cf-purge.sh and
  cf-setup-cache.sh create and purge the cache rule.
- src/lib/cloudflare-api.ts: purgeCacheByTags/purgeCacheByUrls.
- Purge hooks after catalog exports (public + gamedata) and on shop, team,
  guild, photo and rare-values edits; ci-deploy purges after each release.
- src/proxy.ts excludes the imaging/images docs from the middleware matcher.

# ─── EpicNabbo CMS — nginx site config ───
# Source of truth: deployment/proxy/nginx-cms.conf in the EpicNext-Cms repo.
# Installed at /etc/nginx/sites-available/cms.conf by scripts/nginx-sync.sh.
#
# Ingeladen binnen http{} uit /etc/nginx/sites-enabled/*.conf.
#
# PRINCIPE — één eigenaar per URL-klasse:
# * Alleen nginx (dit bestand) mag Cache-Control toevoegen voor routes die
# een publieke, gedeelde cache toestaan.
# * Alles wat de app zelf (src/proxy.ts) als no-store stuurt, blijft no-store.
# * Er is GEEN byte-cache meer (geen proxy_cache_*): de app deed ooit zelf
# al single-flight/stale-while-revalidate in src/lib/cache.ts. Daarmee is
# "dubbele cache" (nginx HIT naast de app) structureel onmogelijk.
# * De headers die hieronder staan zijn de enige Cache-Control die een
# client/CDN te zien krijgt; er wordt nooit een tweede toegevoegd.
# ─── Maps (moeten op http level staan) ───

# ─── Cachebeleid: één plek die beslist of een antwoord gedeeld mag worden ───
#
# Waarom op nginx: Next.js overschrijft `Cache-Control` op dynamische route
# handlers (next/dist/server/send-response.js weigert een al aanwezige header
# te overschrijven) en src/proxy.ts zet die paden bovendien op no-store. Deze
# maps nemen de publieke beslissing daarom expliciet over van de app, zodat
# browser + CDN daadwerkelijk cachen — met één enkele header.
# Nooit als "publiek" aankondigen als er een sessie aan hangt. NextAuth v5
# zet `__Secure-authjs.session-token` (en `authjs.*` zonder prefix); de
# Nitro-client gebruikt een eigen cookie. Elke cookie waarvan de naam op
# session-token eindigt of met authjs. begint telt als "ingelogd", plus elk
# Authorization-header. Zo kan een persoonlijke variant nooit publiek worden.

# 2. proxy_read_timeout — de default van 60s beëindigt een stroom die
# tijdens een batch-job even stilvalt, waarna de client reconnectt en
# opnieuw 504 krijgt: een reconnect-loop die de app juist belast.
# 3. send_timeout — de server-level 10s meet de pauze tussen twee writes.
# Een stream die 25s pingt, of een batch die minuten niets doet, wordt
# daar dus losgekapt. Daarom hier een eigen, ruime waarde.
