fix: crate::extensions::idle::Handle::wait() uses a 29 minute timeout

[DavidEichmann]

The timeout was incorrectly set to 24 hours. This has been changed to 29 minutes to reflect the documentation on Handle struct and the reccomendation in RFC 2177.

[DavidEichmann]

I have observed in my production system that Handle::wait(..) returns Ok(..) after about 30 minutes, which is immediatly followed by a Handle::done() that returns a connection lost error. I suspect that Handle::wait() returns Ok(ManualInterupt) when the server drops the connection due to a timeout. As a separate issue, we should consider if Handle::wait() should return Ok(ManualInterupt) or Err(/* connection lost */).
