Subject: [PATCH 1/3] fix: use json_dumps to handle Decimal types in
 attached_clients response

DynamoDB returns numeric fields (createdAt, lastAccessTime) as Decimal
objects, which the standard json.dumps cannot serialize. Swap to the
existing json_dumps utility which uses DecimalEncoder to convert Decimals
to floats.

Subject: [PATCH 2/3] fix: use json_dumps in account_device and account_devices
 routes

Same Decimal serialization issue as account_attached_clients: both routes
serialize DynamoDB data that may contain Decimal values for createdAt and
lastAccessTime fields.
