Better partial templates by passing in Model instances

Currently, there are lots of heavy-work done by the controllers as well as views. The shared partials make it easy to be re-used, but there are lot of redundant variables (like, `name`, `description`, ...) which can be easily replaced by Model instances (like, `@table`, `@collection`, ...).

The issue mentions controllers, views, shared partials, and model instances such as @table and @collection, but names no files or tests. Start by tracing the partials and the controllers that provide their redundant variables. Done means the shared partials receive the relevant model instances instead of separate variables, with existing behavior preserved.
