fix: state corruption of import accounts drawer

Description

Addresses several state corruption issues related to import accounts drawer in account management, namely state being rendered for the previously opened chain.

Key changes:

Migrates the account import queries to useInfiniteQuery in order to simplify state management
Resets component state when a different chain is being managed
Uses an actually unique key for account rows (instead of account number which is shared across different chains)
