ui: ./dev ui watch fails on missing protobuf files

[dhartunian]

This appears to be related to the complex bazel rules that govern the protos.d.ts and protos.js files that we generate for the UI. These are copied correctly into working directories in bazel, but not into the sandboxes as expected.

failed to arrange files for watchers: open /private/var/tmp/_bazel_davidh/d61affdd093572eb0c41c4220c20a747/execroot/com_github_cockroachdb_cockroach/bazel-out/darwin_arm64-fastbuild/bin/pkg/ui/workspaces/db-console/src/js/protos.js: no such file or directory

I've tried running a number of bazel rules manually to make these files appear but none of them seem to do the trick.

The issue seems to be that the arrangeFilesForWatchers function doesn't look for the files in the right place. The files in the bazel sandbox are under the crdb-protobuf-client subdirectory.

However, there's still more to investigate here as the ccl directory doesn't contain the expected libs after the oss ones are built.
