Subspace templates: select new template for existing subspace

[SimoneZaza]

Description

As an admin of a Subspace, I also want to be able to apply these amazing templates to my subspace, without having to create a new subspace

Acceptance criteria

We'll reuse the "change innovation flow" flow for this!

• [ ] In Manage Innovation Flow Dialog, Change button "Select different flow" to "Find template"
• [ ] Clicking on the button opens the standard library dialog, with first the templates from the space library and then the templates from the global library
• [ ] Selecting a template opens the template preview dialog
• [ ] Clicking on use opens a confirmation dialog, in which people can choose to add the collaboration tools or not
• Note that there won't be an option to only add the collaboration tools, or to remove the existing collaboration tools by replacing them with the new
• [ ] What happens to the original callouts:
• The existing callouts are either brought to the first phase of the new flow, or
• if the flow state is the same, they remain in the same flow state as they were
• This last part is not critical, but I imagine this will happen out of the box. That would be great, but if it's easier always to bring all existing callouts to the first phase, that is also fine. Please flag if this is the case as the text would need some adjustments.
• [ ] When confirmed, close all dialogs, bring user to the subspace screen with updated flow/tools

Server work: We need a Mutation similar to updateInnovationFlowStatesFromTemplate, it should receive the subspaceId, the collaborationTemplateId (or spaceTemplateId), and the flags needed: copyCallouts, (copyContext in the future) ...
