Entrypoints call ops

[glass-ships]

Description of work:

Entrypoints now call operation stubs directly.
Some tweaks to fix tests and make arguments ordered consistently.

Check all that apply:

• updated documentation
• Source added/refactored
• Added unit tests
• Added integration tests
• Verified that tests requiring the /SNS and /HFIR filesystems pass without fail

⚠️ Manual test for the reviewer

(Instructions for testing here)

Check list for the reviewer

• best software practices
  • clearly named variables (better to be verbose in variable names)
  • code comments explaining the intent of code blocks
• All the tests are passing
• The documentation is up to date
• code comments added when explaining intent

i think this probably calls for its own class of error. Feels like these entry points could use their own hierarchy of error to keep this sorted
