Search Field in the navigation and functionality

[KenavR]

Dependencies:

• front-end: title-card (Basic Elements #8), content list (Series/Movie Title Card #9)

• maybe back-end: Endpoint for search functionality (spec: REST Interface #7, impl: #...)

Add a search field to the navigation and think about how to implement the search functionality. I see two possibilities if the “content list” (#8) contains every entry a client-side search/filter may be possible. If we decide to lazy load additional entries or separate the list, a back-end search may be required.
