Shared Spaces lead with Topics
A Shared Space now opens on its Topics, not a tabbed settings screen. The landing is a searchable grid of Topic cards — each showing how many Memories it holds, description, latest capture, and who's been filing into it (including how many an agent auto-filed). Open a Topic to read and capture only within it (a Memory you add there is filed into that Topic), or hit "All Memories" for the flat feed. Type filters and the per-memory Topic reassign carry over. Everything administrative — Details, Topics, Members, and an Owner-only Insights tab — now lives on a dedicated Space settings page reached from the header.
