Add shared ViewHistory<V> utility class that provides a proper navigation
stack for rApps with hierarchical views. Replaces hardcoded data-back
targets with stack-based back navigation across 10 rApps: rtrips, rmaps,
rtasks, rforum, rphotos, rvote, rnotes, rinbox, rschedule, rcart.
Rename rWork module to rTasks — directory, component (folk-tasks-board),
CSS, exports, domains, and all cross-module references updated.

All 22 module directories under modules/ now match their module IDs
(e.g. modules/cart → modules/rcart, modules/canvas → modules/rspace).
Updated all import paths, vite build config, HTML template asset refs,
docker-compose standalone commands, and .gitignore accordingly.
