Stop these two warnings from happening on every reconcile loop

```
metadata.name: this is used in Pod names and hostnames, which can result in surprising behavior; a DNS label is recommended: [must not contain dots]	{"controller": "temporalworkerdeployment", "controllerGroup": "temporal.io", "controllerKind": "TemporalWorkerDeployment", "TemporalWorkerDeployment": {"name":"all-at-once-rollout-2-replicas","namespace":"test-integration-20250903200429"}, "namespace": "test-integration-20250903200429", "name": "all-at-once-rollout-2-replicas", "reconcileID": "5cdf5048-693b-4f77-90ca-30d42444748e"}

We should not cut a release with known log spam.
I kept the build ids in Temporal as having any characters at all, but
when converted to a Deployment or Pod name, clean them to DNS only.

<!--- add/delete as needed --->

1. Closes #134

2. How was this tested:
Unit tests for the build id change
Checking logs on integration tests for the other changes. I'd like to
make the tests error if there are too many warnings, but the log level
is `info` on these, so I'm not sure how to make that work

3. Any docs updates needed?
<!--- update README if applicable
      or point out where to update docs.temporal.io -->
