User-facing rename across 20 files:
- Layout title/meta: "CapaKraken — Resource & Capacity Planning"
- Sidebar logo: "CapaKraken" with "RESOURCE & CAPACITY PLANNING"
- Sign-in page: "CapaKraken Control Center", "Sign in to CapaKraken"
- PWA manifest: name + short_name
- PDF reports: footer text
- Install prompt: "Install CapaKraken"
- AI assistant system prompt
- Webhooks test payload
- Email subject lines
- Tooltips, descriptions, empty states

NOT changed (technical identifiers):
- Package names (@planarchy/*)
- Import paths
- Database names
- Docker container names
- localStorage keys
- Domain URLs
- CLAUDE.md
