- AI advice handler now sends both `x-api-key` and `Authorization: Bearer`
so proxy gateways (e.g. chat.trollllm.xyz) accept the request. Native
Anthropic ignores the extra header.
- Remove `lg:sticky lg:top-20` from listing detail contact card — sidebar
now scrolls with the page.
- Fix missing Vietnamese diacritics on AI estimate button:
"Dinh gia AI" -> "Định giá AI", "Dang dinh gia..." -> "Đang định giá...".
Tests updated accordingly.

Build the valuation page at /dashboard/valuation with form input,
AI-powered price estimation results, comparable properties display,
and valuation history. Add "Dinh gia AI" button to listing detail
sidebar for quick per-listing estimates.
