[#28187][prism] worker shutdown, cleanup, log fail, port spec, grpc recv size

[lostluck]

Some fixes while trying to use the experimental Swift SDK against prism.

• Use an actual loopback address for endpoints instead of the net package listener default of unspecified.
  • IPv6 uses "[::]" to mean an unspecified address, which Go then treats as the loopback address. This isn't true across all SDKs, so we must explicitly indicate the loopback address.
  • Note: We create the server to listen to any traffic to that port however, so other connections, possibly off the machine, remain valid.
• Increase default receive buffer to max.
• Fail jobs if the SDK worker doesn't connect after 1 minute.
• Error job failures on log on slog side.
• Minor log clean up, to a debug log.
