ui: display depth and other filters independently

As the comment says:
In hledger,
- reportopts{depth_} indicates --depth options
- reportopts{query_} is the query arguments as a string
- the report query is based on both of these.
For hledger-ui, currently, we move depth: arguments out of reportopts{query_}
and into reportopts{depth_}, so that depth and other kinds of filter query
can be displayed (and controlled) independently.
