`getLogs` for multiple accounts simultaneously. For now only used for
new transfers detection. Detection of `new` transfers has been changed,
now they are searched from head and forward. Previously they were
searched from last scanned block forward.
Add new APIs to track if valid pairings are available to be used
by application not to run WalletConnect SDK if not needed.
Closes status-desktop: #12794
The only place where appDB is used in wallet is activity,
which refers to `keycards_accounts` table. So a temporary
table `keycards_accounts` is created in wallet db and updated
before each activity query.
