Some ticket-related REST API endpoints have been removed or changed in hoprd 4.0

[NumberFour8]

The following endpoints were removed:

• GET channels/{{channelId}}/tickets
• DELETE /tickets/statistics
• GET /tickets

The following endpoints were changed to return HTTP 202 instead of 204:

• POST /tickets/redeem
• POST /channels/{{channelId}}/tickets/redeem

In addition the fields redeemedValue and rejectedValue in the response of GET /tickets/statistics are deprecated and should be queried via Blokli instead.
