refactor!: support RUB only (WealthLedger/main#55)

Filter non-RUB data at ingest, collapse per-currency collections into single RUB Money, drop currency from TbankPortfolioValuePoint, remove NON_RUB_ACTIVITY and screener currency filter.

BREAKING CHANGE: per-currency API fields replaced with single RUB Money; stock screener currency param removed.
