Develop a more robust name search workflow

[jayhill]

The basic name search functionality that we have today does not serve the real-world use cases for pro bono attorneys working on record expunction.

Must-haves:

• work around the 200-result limit (divide searches by counties if bumping up against the limit)
• provide post-filtering, where results are filtered after data retrieval (middle name/initial, birth year, etc.)
• create and manage named sets of results under a client record
• add to results with another search (by case number or name; honor existing include/exclude settings when results overlap)
• remove from results (hide)
• show hidden results (current session only)
• new search (clear current working set, which is already saved)
• delete client (with "are you sure?" prompt)
• export client cases to .xlsx
• figure out the structure/navigation between search and case management — do we have ad hoc and client modes on the search screens, or what?
