Item Add: Navigate to the new Item once added

[jimtng]

This PR changes the navigation / where the user is sent to after creating/adding a new item.

Currently, if you go to Settings -> Items -> Add -> Save, you'll be brought back to the Items list (back navigation).

• If the user wants to add another item - it's easy, they can click + again to add another item. No problems.
• But if the user wants to edit that new item, e.g. to edit metadata, add a link, etc. they would need to scroll around, or do a search for the item, click on it to get to that new item.

This PR changes this behavior so that after the new item is saved/added, the user is redirected to the Item Details page of that new item, so they can immediately work on it.

• If they want to add more item, they can click < Back which will bring them to the Add Item page, so they can enter new details and create a new item.
• If they want to go to the items list, they can just click cancel or Back again.

I think this workflow is more streamlined whether the user wants to add one item or multiple items.

This PR doesn't change the navigation behavior when editing an item. As previously done, the user would be sent back to the previous page, which would be the Item details. In other words: Settings -> Items (list) -> Item Details -> Edit -> Save -> Back to Item Details.

Seems reasonable.
WDYT @ghys ?

Would it be worth requesting something similar for Things too, at least when creating a Thing manually (e.g. Generic MQTT Thing)? I find that even more annoying than the Item behavior, perhaps because I rarely create an Item like that. Maybe a separate issue should be opened for that.

[florian-h05]

Good point, Rich 👍
Instead of opening an issue, let’s ask Jim if he wants to change that right now.

[jimtng]

Maybe open a separate issue..it will be in a different pr. Thanks
