feat(phase4+5): role hierarchy, tenant config, fallback material, dead code removal
Phase 4.1 — Role Hierarchy:
- UserRole enum: add global_admin (platform operator) + tenant_admin
(per-tenant admin); keep legacy 'admin' for backward compat
- Role sets: ADMIN_ROLES, TENANT_ADMIN_ROLES, PM_ROLES, RLS_BYPASS_ROLES
- New auth guards: require_global_admin(), require_tenant_admin_or_above(),
require_pm_or_above(), is_admin(), is_privileged()
- Legacy require_admin / require_admin_or_pm now check both old+new roles
- Migration 049: ADD VALUE global_admin + tenant_admin with AUTOCOMMIT
workaround; backfills admin → global_admin
- Seed: new admin users created with global_admin role
Phase 4.3 — RLS bypass updated for global_admin in get_db + set_tenant_context
Phase 4.4 — Tenant Feature Flags:
- Migration 050: tenant_config JSONB on tenants table
- Tenant model: tenant_config field + get_config() accessor
- Defaults: max_concurrent_renders=3, fallback_material, invoice_prefix etc.
Phase 5.1 — Fallback Material:
- blender_render.py: replace PALETTE_LINEAR/PALETTE_HEX/_assign_palette_material
with _assign_failed_material() → SCHAEFFLER_059999_FailedMaterial (magenta)
- Unmatched parts now logged explicitly before rendering
Phase 5.2 — Remove EEVEE fallback:
- render_blender.py: EEVEE→Cycles silent retry removed; hard failure on EEVEE error
Phase 5.3 — Remove Blender version check:
- render_blender.py: deleted MIN_BLENDER_VERSION = (5, 0, 1) constant
