fix(freelancer-directory): delete the dark anonymous-contact modal; retire hello@ -> support@ site-wide

Two user decisions (2026-11-03). The page is live.

1. The anonymous-contact modal is removed in full, not just its gate: its markup and
   comment, the .contact-modal and .dev-anon-btn CSS, the JS (modalEls, openContactModal,
   closeContactModal, initContactModal, enhanceContact), the two init-time calls and the
   per-card render call. ODOO_EXPERTS_QUOTE_WEBHOOK is deleted — the only readers were the
   two gates (initContactModal, enhanceContact) and the postTo inside the modal's own
   submit handler; nothing else read it. The modal's lede ("We pass your request on ...")
   goes with it, so no relay copy survives. Kept on purpose: the invite relay form and
   ODOO_EXPERTS_INVITE_WEBHOOK, the OCA filter + badge, ODOO_EXPERTS_WEBHOOK, and the
   card's direct "Email this freelancer" chip.

2. hello@odoo4projects.com is retired site-wide: 24 occurrences (mailto + visible text)
   become support@odoo4projects.com, and the 12 support@ODOO4projects.com case variants
   are normalised to lower case. oliver@odoo4projects.com is a freelancer's own published
   contact address on their card and is left untouched.

Tests run: verify-html.py PROBLEMS 0; check-inline-js.py OK; competitor QC exit 3 with 74
pre-existing hits and 0 added; impeccable detect 1 -> 1 (identical, 0 new).
