Looks good. A couple notes as I was reading through the files:

1. hs.things.list() will return the response envelope for only the first page of items. If you want to get the full list use .listAll() to get it in a response envelope or .listAllItems() to unwrap it and get just the full list of items or null
2. There's a TODO in the router/guards for thing.ownsThing. The thing schema no longer has ownsThing since all access control is handled on the workspace level now. Take a look at the router.ts file in the data-management-app for how to route based on AllAuth flows if you need this functionality before Ken and I implement OpenIDConnect here in 2 or 3 months.
3. Optional personal preference but @hydroserver/client exposes a createHydroServer convenience function that will create a global hs instance for you and manage the a persisted session so you don't have to save hs in a Pinia store and import the store and pinia helpers in each component. See the data-management-app main.ts if you're interested
