market data: switch to Yahoo v8 chart, drop delisted tickers

Browse source 
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.
