refactor: replace srv-web-7-7-dns-records with sys-dns-cloudflare-records

- removed obsolete role `srv-web-7-7-dns-records` (README, meta, tasks)
- updated Gitea role to use `sys-dns-cloudflare-records` with explicit record vars
- updated web-opt-rdr-www role to use new DNS role with zone detection (`to_zone`)
- added REDIRECT_WWW_FLAVOR var to support "edge" flavor selection
