WS2-3129 Enable anchoring as part of the CERAMIC_RECON_MODE

I'm going to hold off on reviewing this until CI is green, looks like there are still some remaining issues right now

I did not have to make changes to the code other than enabling the anchor when using recon, but I did have to adjust the test setup. A common modification was to add some delay, which is why you will see it in some tests. Ready to be reviewed by @stbrody and @nathanielc.
