Missing some apis for orders, trades, terms for lending apis

[thanhvk]

• /orders: to get the user's order list. (ok)
• /trades: to get the user's trade list.
• /terms: to get term list. (ok)

[thanhvk]

/trades/history need to change from requiring term and lendingToken to optional.

I have fixed it devnet.

[thanhvk]

• In the /orders api tradeId always is 0
• The /trades/history api and lending_trades websocket also missing tradeId

we need to fix it

[thanhvk]

1. The lending_trades websocket return empty tradeID in case type is UPDATE (type `INIT is ok) as below:

2. The /terms api return duplicate data as below:

Expect: [60, 86400, 604800, 2592000]
