Remove post added / edited confirmation screen

[petersalomonsen]

The newly introduced screen confirming that post was successfully added/edited leads to extra steps, and slows down the experience when creating/editing multiple posts.

After a post transaction is successfully executed you should be returned directly to the created / edited post in view mode ( no editor ). Either in the feed, if that's where you came from, or directly to the post.

The reason for the new confirmation screen is for pure technical reasons, to remove the draft state and clear the transactionHashes query string parameter ( as written in the PR where it was introduced: #197 ).

It would be better if this parameter could be cleared by an automatic redirect, but this is not possible in NEAR social VM as of today, so a feature for this would need to be requested there.

Another alternative would be to keep the transactionHashes parameter in the query string, but clear the draft by inspecting the submitted content in the transaction and comparing it with the draft, and only clear the draft if it matches. This would also serve as a better confirmation for that the post is actually edited/submitted successfully. But without clearing the transansactionHashes then it would be preserved in the query string for future posts, and also if reloading the view, it would also look up that transaction, and it's unclear how that would work with multiple posts, so a redirect to clear the query string parameter would be appropriate in any case.

Thank you @petersalomonsen for creating this. I added the Has Dependency tag since there is work required on the NEAR Social VM first: NearSocial/VM#93.

Update the estimation to 2 weeks as also count work in social VM

After learning more about the VM, I think maybe what we want is cache invalidation after a transaction.

NearSocial/VM#156 does this if the user is signed into the devhub contract, which can be tested in the preview URL.
