Post search (#1206)

* Reworked the search build from two years ago. Fleshed out the UI for ipad view and added themed components. SearchView.swift contains all the code for the feature. ForumsTableViewController was updated to conditinoally show the search button (if user has pms). AnnouncementPersistence.swift was updated in order to get the build working in this version of xcode 16.4.

* Addressing PR comments. Tried adding a fixture for the search page for previews, but ended up using a simple solution for the time being.

Resolves #23.
