 Params Description:

+- data_type: The data type of the property type, including: bool, byte, int, 
long, float, double, decimal, text, blob, date, uuid. The default data type is 
`text` (Represent a `string` type). `decimal` holds an exact decimal number 
(Java `BigDecimal`): at most 128 significant digits and a scale of at most 128 
in either direction; it is sent and returned as a plain JSON number with every 
digit, so a client must not parse it as a double

Review Comment:
   ⚠️ Important. This says DECIMAL requests and responses both use JSON 
numbers, but paired server PR #3209 at head 
0bb7724a406d9ee49ab5bfee719aa440ee6ab002 serializes REST BigDecimal responses 
as JSON strings. Please distinguish accepted exact JSON number/string inputs 
from string responses, and update the parallel Chinese paragraph too. Evidence: 
server JsonUtil registers BigDecimalSerializer, whose serialize() calls 
writeString(); JsonUtilTest.testSerializeBigDecimal() asserts quoted output.
