Update some ticket buyer params

[vufon]

Related issue: #2455
1. Add param maxticketprice
Add the parameter maxticketprice to enable control over halting ticket purchases when ticket prices are excessively high
The parameter can be configured in the configuration file with the name: ticketbuyer.maxticketprice

• If value = 0 (default value): The system will proceed with ticket purchases as it did previously
• if value < 0: param error
• if value > 0: The system will cease ticket purchases if the ticket price surpasses the specified threshold

2. Shorten the ticketbuyer.balancetomaintainabsolute param name
The parameter name was unnecessarily long, so I have adjusted it to 'ticketbuyer.balancetomaintain.'
The old name remains supported and valid for backward compatibility. However, there will be a notification about updating to the new param name
warning msg:
“ DCRW: The 'ticketbuyer.balancetomaintainabsolute' attribute in the config file is outdated. You should update it to 'ticketbuyer.balancetomaintain'”

Thanks for your contribution. I'd recommend splitting this into two PRs because these are two distinct changes which can be discussed/reviewed/merged separately without blocking each other.
