Add client-side search to data dictionary page

[jdangerx]

Overview

See #3851.

We have 227 tables and several thousand columns in our data warehouse. While we've attempted to provide some structure via the raw/core/out naming scheme, it's still confusing and overwhelming to figure out whether we have data that's relevant to someone's needs.

Adding a client-side search engine is a simple way to make this process a little bit nicer.

Success criteria

• keyword search works to filter tables
• table title, table description, and table columns are weighted differently in search
• keyword matches are highlighted
• side-by-side result comparison workflow is documented
• search box looks nice
