security: remove sensitive data from logs and escape HTML in tx details

Remove console.log statements that printed transaction IDs, wallet
addresses, payment IDs and payment-proof signatures to the debug log.

Escape all user/chain-supplied fields in buildTxDetailsString before
inserting them into the rich-text table shown in the transaction
details dialog, preserving the intentional <br> line separators in the
destinations field.
