decruft/fix: drop contact page icons + fix white-on-white navbar brand

- page-contact.php: remove the 7 fa fa-* spans (address/phone/email + subscribe/
  chat/pay/guests links all have text labels). Theme-wide FA usage now 0.
- style.css: the brand carries .light{color:#fcfcfc!important}, which beat the
  no-!important body.contact rule → brand was near-white on contact's light
  (#F6F6F6) bg. Add !important to body.contact .site-title a{color:#000} so its
  higher specificity wins; brand is now readable on contact.
