Add the missing tab bar to the canvas page so users can switch between
rApp layers (with full CommunitySync persistence). Add an "rApps"
toolbar group that embeds any of the 18 remaining modules as interactive
iframes directly on the canvas. Switch all module page routes to
renderIframeShell, loading standalone domains inside the unified shell.

Consistent nav headers, button styles, and layout patterns
across calendar, cart, choices, data, forum, funds, inbox,
maps, network, notes, providers, trips, vote, and work modules.

The light theme was causing the header bar to render with a white
background, clashing with the dark-themed module content underneath.
All modules and both shell renderers now default to dark theme.
