Websocket: Add linked_account to block content of confirmation topic

[Exxenoz]

This PR introduces support for including a linked_account field in the block content of the websocket confirmation topic. Specifically:

• The linked_account field is now included for all blocks when the include_linked_account option is enabled.
• For change and epoch blocks, linked_account is set to "0", ensuring consistency with the source field in the blocks_info RPC response.

Issues resolved
This PR addresses the following issues:

• Websocket message is missing the source_account on receive blocks #3523
• Websocket confirmation topic : Add source_account on receive blocks / open blocks #3538

[Exxenoz]

Would it make sense to set linked_account for change blocks to the representative account and for epoch blocks to the epoch link/signer? This could help simplify some issues in block explorer applications, such as:

let relatedAccount = response.message.block.linked_account ?? response.message.block.account;
switch (response.message.block.subtype) {
  case "change":
	relatedAccount = response.message.block.representative;
	break;
  case "epoch": // ToDo: Find epoch link
	relatedAccount = response.message.block.account;
	break;
//--- solved by linked_account
  /*case "receive":
	// @TODO https://github.com/nanocurrency/nano-node/issues/3523 
	relatedAccount = response.message.block.account;
	break;
  case "send":
	relatedAccount = response.message.block.link_as_account;
	break;*/
}
