fix(canvas): disabled module gating + toolbar reorganization
- Remove MODULE_BADGES fallback in tab-bar add-menu (show "Loading rApps..." instead of leaking all modules)
- Block ?tool= URL param from spawning shapes for disabled modules
- Add disabled-module overlay on existing canvas shapes (grayed out + "Module disabled" badge)
- Guard newShape() against creating shapes for disabled modules
- Reorganize toolbar from 10 groups to 9 category-aligned groups:
Write, Embed (core 4), Communicate, Plan, Decide, Spend, Create, AI, Record
- Eliminate duplicate "Connect" groups, slim mega "Embed" group, merge "Travel" into "Plan"
