### Context

I moved a 'Proposed' Gov Action onto the chain for voting. After I had moved it, or 'submitted it for a vote', GovTool directed me to "Go to Dashboard", however, when I clicked the link, I went back to the main Proposals area.

There are multiple problems here:

1. The button tells me to go to the Dashboard, but takes me to the Proposals area, so it's mislabelled
2. When I go back to the Proposals area, I can't find my newly-submitted Action, it has moved to another section, called "Governance Actions"
3. I do not think that users will know where their newly-chained Action has ended up vis-a-vis govtool, but I looked for it in the Governance Actions tab (as I know the dark secrets of GovTool) However, I could not find it without messing with scrolling the screen, and using the filters.
4. When I submitted the Action to the Voting stage, it had my user name, when I found it eventyally under the Governace Actions tab, the username was missing. It should always have this username, so I can recognise it's mine, and in general, things shouldn't lose information as they progress through a system.

This is a multi-part problem, stemming from the fact that the Proposals part of GovTool was designed as a standalone app, and has not been integrated properly to GovTool. Also this issue points out poor default display of Governance Actions on the GA homepage, where a user can't find their most-recently created action without a lot of work.

### Steps to reproduce

1. Create a proposed Action
2. Submit it to vote
3. Click "Go to Dashboard"

### Actual behavior

After clicking "Go to Dashboard", the user is taken to the Proposals page

### Expected behavior

User should be taken to somewhere where they can see their Action, and vote on it.
