fix: resolve 'Failed to parse URL from /me' error in container dry-run deployments

- Always call fillOpenAPIConfiguration when containers are defined, even in dry-run mode
- Set up OpenAPI configuration before calling maybeBuildContainer in the main deploy flow
- Add test to ensure container dry-run works without URL parsing errors
- Add changeset for this bugfix

This fixes the issue where 'wrangler deploy --dry-run' with containers using local
Dockerfiles would fail because OpenAPI configuration wasn't set up before making
API calls during container building.

The fix ensures that the AccountService.getMe() call in loadAccount() has a proper
base URL configured instead of an empty string, preventing the invalid '/me' URL error.

+fix: resolve "Failed to parse URL from /me" error in container dry-run deployments
+
+Fixes an issue where `wrangler deploy --dry-run` with containers using local Dockerfiles would fail with "Failed to parse URL from /me" error. The fix ensures OpenAPI configuration is properly set up before making API calls during container building in dry-run mode.
+
+This change only affects the specific error scenario and maintains backward compatibility.
