fix: fix btc time lock rgbpp transaction query

[ahonn]

The previously implemented RGB++ transaction query logic omitted the BTCTimeLock transaction of L1 -> L2, resulting in the inability to return the RGB++ related CKB transaction.

The PR realizes the search for the CKB transaction containing BTCTimeLock Cell through BTC txid.

The implementation is as follows:

• Get BTC transaction through txid
• Use CKB RPC to query the CKB transaction corresponding to the input containing the BTC transaction
  • For any RgbppLock cell, there are up to two transactions on CKB that contain it. One may be an L2->L1/L1->L1 transaction, and the other may be an L1->L1/L1-> L2 transaction.
  • We can determine which transaction they are by parsing the input/output cell lock script of these two transactions.
  • In this PR, we use the CKB Explorer API to simplify the process
• Get the details of the CKB transaction and determine whether it contains BTCTimeLock Cell output
• Build RgbppTransaction through CKB transactions
