[NOREF] Remove TailScale references

[ClayBenson94]

NOREF

Description

• Removes references to tailscale that were causing occasional lint failures (see this job and this comment)

How to test this change

This is just removing code, so just ensuring that there's no more references to tailscale and that everything boots as expected in CI / with scripts/dev up should suffice!

PR Reviewer Guidelines

• It's best to pull the branch locally and test it, rather than just looking at the code online!
• When approving a PR, provide a reason why you're approving it
  • e.g. "Approving because I tested it locally and all functionality works as expected"
  • e.g. "Approving because the change is simple and matches the Figma design"
• Don't be afraid to leave comments or ask questions, especially if you don't understand why something was done! (This is often a great time to suggest code comments or documentation updates)
• Check that all code is adequately covered by tests - if it isn't feel free to suggest the addition of tests.
