fix: index on principal_stx_txs table for faster /v1/address/{addr}/transactions lookups

[zone117x]

This index speeds up the sql query for the /v1/address/{addr}/transactions endpoint.

Testing this query against a mainnet dev cluster db:

      WITH stx_txs AS (
        SELECT tx_id, index_block_hash, microblock_hash, (COUNT(*) OVER())::INTEGER AS count
        FROM principal_stx_txs
        WHERE principal = 'SP3D6PV2ACBPEKYJTCMH7HEN02KP87QSP8KTEH335.megapont-robot-component-nft'
          AND block_height <= 162751
          AND canonical = TRUE
          AND microblock_canonical = TRUE
        ORDER BY block_height DESC, microblock_sequence DESC, tx_index DESC
        LIMIT 50
        OFFSET 0
      )
      SELECT *,
        count
      FROM stx_txs
      INNER JOIN txs USING (tx_id, index_block_hash, microblock_hash)

With this index it takes 200ms, without it was taking over 2 minutes.
