TASK-13: rApp frontends now inject EncryptID bearer tokens via authFetch()
and gate mutations behind requireAuth() — rvote, rfiles, rmaps all protected.
Demo mode unaffected.
TASK-41: Dynamic shape registry replaces 300-line switch in canvas.html and
165-line if-chain in community-sync.ts. All 41 shape classes now co-locate
fromData()/applyData() with their existing toJSON(), making shape creation
and sync fully data-driven.
TASK-42: Data pipes between shapes via typed ports. Shapes declare
input/output PortDescriptors, arrows connect ports with type checking,
100ms debounce, and color tinting. AI shapes (prompt, image-gen, video-gen,
transcription) have initial port descriptors.
