fix: Misc improvements toscripts/develop.sh (#4995)
* Use new `/healthz` endpoint for checking API liveness* Improved credential handling/retrying in failure scenarios* Separate site (`vite`) logs with prefix and date, additionally this method also disables the `vite` clearing of the screen* Show all interfaces coder API is listening on (due to `0.0.0.0`)* Improved shutdown procedure / interrupt handling
