schema: increase size of column 'value' at table 'account_details' (#6080)

This PR increases the column value at table account_details from 255 chars to 4096, matching with the value allowed in the API command for updating the configuration of accounts.

When the value length is bigger than 255, the following log is presented right after the updateConfiguration API call:
