Proposing to include the fix for #6568 in v4.8.2.
Issue: getaccount and related APIs return value as a numeric type (int64), which exceeds JavaScript's safe integer range (2^53 - 1). JS clients using JSON.parse() silently lose precision on large balances.

Solution agreed in #6568: Add a companion value_string field (string representation of the same int64) to avoid breaking existing consumers while resolving the precision issue.

The fix is backward-compatible (additive only) and low-risk, which makes it a good candidate for a patch release. Please let me know if this should be tracked here or handled separately.

Hi, for the first task, we will create the release_v4.8.2 branch from develop.
The difference between develop and master can be found here.
Is the develop branch in a satisfactory state for the next release?
If there is any problem, please list it here.
If not, we’re planning to create the branch in two days.
