Save WorkflowTemplate.name in the created WorkRequest and main parameters, adapt workflow filtering interface and list
When a Workflow is created via `WorkRequest.create_workflow()` the WorkflowTemplate.name is not saved in the WorkRequest. It needs to be stored so it can be displayed in the list of work flows (or some other way to retrieve the `WorkflowTemplate.name` from the WorkRequest). See https://salsa.debian.org/freexian-team/debusine/-/merge_requests/1428#note_555271 for more context. It's also needed to keep the relevant "main input parameters" (as seen in https://freexian-team.pages.debian.net/debusine/reference/devel-blueprints/monitor-workflows.html) Once done, adapt the workflow filtering interface and workflow list to display the WorkflowTemplate.name and the main parameters as per the blue-print. Part of #400, report time in #400.
