refactor: rpc: set TxToJSON default verbosity to SHOW_DETAILS

`TxToJSON()` and `TxToUniv()` are only to be called when we want to
decode the transaction (i.e. its details) into JSON. If `TxVerbosity` is
`SHOW_TXID`, the function should not have been (and currently is not)
called in the first place.

There is no behaviour change, current logic simply assumes anything less
than `TxVerbosity::SHOW_DETAILS_AND_PREVOUT` equals
`TxVerbosity::SHOW_DETAILS`. With this change, the assumptions and
intent become more explicit.
