init: lab project bootstrapped from isletmem-kovakcrm

- CRM domain modules removed (customers, services, software, calendar, tasks, invoices, leads, finance, etc.)
- DLS branding: package name=lab, logo wordmark, sidebar nav, header CTA
- Tenant layer extended with kind dimension (lab|clinic) + requireTenantKind helper
- Schema rewritten for DLS domain: jobs, job_files, job_status_history, prosthetics, connections, finance_entries, notifications
- Onboarding form: clinic/lab account-type selection + auto-generated memberNumber
- Placeholder routes for jobs/{inbound,outbound,new}, products, finance, connections
- PDF spec + spec.md under belgeler/
- db: lab database + 13 collections + indexes + storage bucket (job-files) provisioned via Appwrite MCP
