dawarich: dedicated 100/1000 Traefik rate limit (default 10/50 429'd page loads)

Viktor saw dawarich throwing 429s through Traefik and asked to loosen
the burst for it. The access log confirms the burst pattern: one page
load fires the whole fingerprinted-asset tail (SVG store badges,
favicons, webmanifest) from a single client IP and trips the default
10 req/s / burst 50 limiter (repro: 80 parallel GETs -> 28x 429).
Same remedy as ha-sofia, ActualBudget, noVNC, tripit, health and
authentik: dedicated dawarich-rate-limit middleware (average 100 /
burst 1000) + skip_default_rate_limit on the dawarich ingress. Also
updates the networking.md middleware enumerations (adding the
previously undocumented tripit/health limiters alongside dawarich).
