ConfigMap adguard-defaults holds desired settings (upstreams, bootstrap DNS,
filter lists, rewrites). Init container merges them into the PVC config on
every pod start — no more manual kubectl edits needed.
- Switch upstreams to Cloudflare + Google DoH (Quad9 was failing)
- Bootstrap DNS IPv4-only (removes IPv6 timeout errors)
- Add OISD Big, EasyList, EasyPrivacy filter lists
- Fix DNS rewrites pointing to old IP 192.168.0.105
