[ci skip] right-size all pod resources based on VPA + live metrics audit
Full cluster resource audit: cross-referenced Goldilocks VPA recommendations,
live kubectl top metrics, and Terraform definitions for 100+ containers.
Critical fixes:
- dashy: CPU throttled at 98% (490m/500m) → 2 CPU limit
- stirling-pdf: CPU throttled at 99.7% (299m/300m) → 2 CPU limit
- traefik auth-proxy/bot-block-proxy: mem limit 32Mi → 128Mi
Added explicit resources to ~40 containers that had none:
- audiobookshelf, changedetection, cyberchef, dawarich, diun, echo,
excalidraw, freshrss, hackmd, isponsorblocktv, linkwarden, n8n,
navidrome, ntfy, owntracks, privatebin, send, shadowsocks, tandoor,
tor-proxy, wealthfolio, networking-toolbox, rybbit, mailserver,
cloudflared, pgadmin, phpmyadmin, crowdsec-web, xray, wireguard,
k8s-portal, tuya-bridge, ollama-ui, whisper, piper, immich-server,
immich-postgresql, osrm-foot
GPU containers: added CPU/mem alongside GPU limits:
- ollama: removed CPU/mem limits (models vary in size), keep GPU only
- frigate: req 500m/2Gi, lim 4/8Gi + GPU
- immich-ml: req 100m/1Gi, lim 2/4Gi + GPU
Right-sized ~25 over-provisioned containers:
- kms-web-page: 500m/512Mi → 50m/64Mi (was using 0m/10Mi)
- onlyoffice: CPU 8 → 2 (VPA upper 45m)
- realestate-crawler-api: CPU 2000m → 250m
- blog/travel-blog/webhook-handler: 500m → 100m
- coturn/health/plotting-book: reduced to match actual usage
Conservative methodology: limits = max(VPA upper * 2, live usage * 2)
