refactor price context to fetch multiple tokens (#1573)

* refactor price context to fetch multiple tokens

* fixes

* move tokenIds to app config

* make conversion work

* conversion for all user tokens, hide if 0

* different user balance key tactic

* remove NFT gas estimation

* closes #1633

* small simplification in getCoingeckoTokenId logic

* basic Prices provider test

* mock some hooks

* mock MarketMetadata in all tests
