Add movement gallery wings with period interiors and expand timeline features.

Movement galleries split large catalogs into chronological wings (~55 works), use era-themed 3D interiors with side-wall windows, wing navigator on the back exit, and front archways between wings. Also adds painting annotations, timeline event guides, portrait hover highlights, and documentation/API updates.
