Story: Add a Venue

As a Host, I want to create and define a new venue, so that I can manage the physical locations where my events take place.

Acceptance Criteria

I can specify a name for the venue (e.g., "My House", "Lake Cabin").
I can provide an address for the venue.
Once created, the venue should be available to be associated with an event.
I should be able to add one or more named bar areas to the venue (e.g., "Kitchen Counter Bar", "Outdoor Tiki Bar").
I should be able to add one or more named storage areas to the venue (e.g., "Pantry", "Garage Fridge", "Basement Cellar").
For each storage area, I can specify its type (e.g., Dry, Cold, Wet).
