Refine transfer data schema to classify transfer data derived from Unlock events

[purplesmoke05]

Close #700

DB

• Added new message column with index to idx_transfer table, separate from existing JSON data field

API

• Detailed transfer data schema on Transfer List API to classify transfer data derived from Unlock events

class TransferBase(BaseModel):
    transaction_hash: str
    token_address: str
    from_address: str
    from_address_personal_information: Optional[PersonalInfo] = Field(...)
    to_address: str
    to_address_personal_information: Optional[PersonalInfo] = Field(...)
    amount: int
    block_timestamp: str

class Transfer(TransferBase):
    source_event: Literal[TransferSourceEventType.Transfer] = Field(
        description="Source Event"
    )
    data: None = Field(description="Event data")

class UnlockData(BaseModel):
    message: Literal[
        "garnishment",
        "inheritance",
        "force_unlock",
    ]

class UnlockTransfer(TransferBase):
    source_event: Literal[TransferSourceEventType.Unlock] = Field(
        description="Source Event"
    )
    data: UnlockData | dict = Field(description="Event data")

• Added GET query to /{bond or share}/transfers/{token_address} for searching by message field.

Batch

• Fixed to store message column when saving Transfer records.

Since there may be cases in the future where it is necessary to parse messages for events other than UnLock, I thought it would be better to use a structure name such as "DataMessage".

Renamed the schema to DataMessage for future reusability d5509f1
