The picker row (page list, Clear, Done) is gone. Each Companion page is now
its own + entry, titled with the page's name, showing the whole page minus
page up/down. The grid icon switches the tile to choosing: click buttons to
take them out or put them back, click the icon again when done. The gear
holds one switch, Page layout (Companion's rows and columns, or packed).
- Tiles follow their page by Companion's page id and buttons by row/column,
so inserted pages and re-imported pages keep showing.
- A tile remounted after a settings change asks GET /state for the snapshot
the already-open stream sent, instead of waiting blank.
