fix: add opt-out flag to fides init

[mikemechanic1337]

Summary

• Closes #4703
• add --opt-out flag to fides init so non-interactive setups can disable analytics
• guard against mixing --opt-in/--opt-out and thread the new option through config creation
• extend analytics consent unit tests and update the changelog entry

Testing

• pytest tests/ctl/core/config/test_create.py

Manual Verification

1. Ensure Docker Desktop is running and copy example.env to .env if needed.
2. Launch the dev stack through nox and drop into the webserver container shell: nox -s dev -- shell. Once the shell opens, run:
   • mkdir -p /tmp/fides-init-check && cd /tmp/fides-init-check
   • fides init --opt-out
   • grep analytics_opt_out .fides/fides.toml (should read true)
   • fides init --opt-in --opt-out (fails with "--opt-in and --opt-out cannot be used together")
   • exit to leave the container shell.
3. Execute the control-plane unit tests via nox: nox -s pytest -- ctl-unit. (This covers tests/ctl/core/config/test_create.py; alternatively run the file directly inside the container if preferred.)
4. Tear everything down when finished: nox -s teardown -- volumes.
