Clear version warning immediately after successful deploy (#519)

* Clear version warning immediately after successful deploy

* Suppress version check for 45s after deploy to avoid stale warning

* TEMP: bypass source build suppression for testing

* Show spinner for version during post-deploy grace period

* Remove temp bypass, restore source build suppression
