Update the default state generation of neuroglancer

[manasaV3]

Motivation

To update the neuroglancer visualization config state to incorporate changes made to improve user experience.

Changes to be incorporated:

1. Reformatted layout of the neuroglancer page (Reach out to Metacell about this)
2. opacity slider for additive blending (feat: Add default opacity to 1 and blend to additive (CC-165) cryoet-data-portal-neuroglancer#27)
3. hide shader code from users (Add option to hide/show code block google/neuroglancer#688, feat: Add default value to false for code editor display cryoet-data-portal-neuroglancer#29)
4. hide the opaque, single-color background of the orthoplanes in the 3D view of the tomogram (feat: option to hide cross section background in 3D slice views google/neuroglancer#663)

Changes Required

As all of the integrations to the in the cryoet-data-portal-neuroglancer, have default values, this should not require any additional values to be passed during the state generation.
The version of cryoet-data-portal-neuroglancer package included with the ingestion, should be be updated to include the new changes, and the config generation should be validated for any regressions. This can be done by comparing it to the existing rendering in prod for comparing the layers generated visually.

What done looks like

• All of the config changes have been incorporated.
• The neuroglancer config has been regenerated for all the dataset and runs in staging and pass the validations
• The neuroglancer config has been updated in prod

Implementing #1431 would address most of the requirements for this issue.
