Enable pyright in CI for full source tree

[rtuck99]

Currently after migrating to python-copier-template (see #378) we had to disable the default running of pyright against the full source tree, in favour of doing diff-quality against new checkins

As of this time there are ~197 pyright failures, if we fix these we should be able to remove diff-quality and revert to the standard copier-template of doing 100% check in lint CI step

Acceptance Criteria

• Pyright violations are fixed and lint CI runs tox -e type-checking instead of diff-quality
