Subject: [PATCH] market data: switch to Yahoo v8 chart, drop delisted tickers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

v7/finance/quote returns 401 now — Yahoo stopped issuing anonymous
clients the cookie+crumb pair it requires. v8 chart still answers
without auth, one symbol per request instead of one bulk call.
Also dropped SBER/GAZP from the tracked symbols; Yahoo delisted
Russian tickers in 2022, so those two always missed anyway.
