feat(search): add skeleton for v2 search

[kahboom]

Description

This PR introduces a skeleton page for v2 search (relates to #157). Note that this is a WIP and not feature complete.

Changes

• Add new Search page component
• Add new route for /search

TBD / To Do / In Progress

• Global search functionality for all components. Normally I might suggest using React context for global-style search, but if we're not sure whether we'll be going with dedicated pages or tabs for each searchable component, then I'll just leave it like this for now until we decide we need it. In this case, we will need to lift the state up to the common ancestral parent, search.tsx, and pass them down as props. @carlosthe19916 what do you think?
• Unit tests with mocks
• E2E tests
