refactor: consolidate RBAC into dojo/authorization package

[Maffooch]

Description

Consolidate every RBAC / authorization concern into a single dojo/authorization/ package. Before this PR, authorization code lived in seven different places: dojo/models.py (RBAC models), 14 per-app queries.py files (get_authorized_*), every view file (@user_is_authorized decorators), dojo/api_v2/permissions.py, dojo/location/api/permissions.py, and dojo/templatetags/authorization_tags.py. After this PR, it all lives in dojo/authorization/.

Net diff: 85 files changed, +3015 / −2113.

What moves into dojo/authorization/

• models.py — 7 RBAC models (Role, Global_Role, Dojo_Group_Member, Product_Member, Product_Group, Product_Type_Member, Product_Type_Group) extracted from dojo/models.py. app_label='dojo' is preserved so no migrations are needed; ~47 import sites are updated.
• api_permissions.py — dojo/api_v2/permissions.py and dojo/location/api/permissions.py merged into one module; originals deleted; consumers and tests rewritten.
• template_filters.py — filter functions extracted from dojo/templatetags/authorization_tags.py. The templatetags module becomes a thin registration proxy.
• query_filters.py + query_registrations.py — registry pattern (~1.9k lines of RBAC filter logic) extracted from 14 per-app queries.py files. Each get_authorized_* becomes a thin wrapper that defers to the registry and falls back to unfiltered querysets when no RBAC backend is registered.
• url_permissions.py + middleware.py — map ~198 URL names to permission checks and enforce them via AuthorizationMiddleware.process_view. Removes @user_is_authorized, @user_has_global_permission, and @user_is_configuration_authorized from 26 view files.
• __init__.py — exports the public surface and triggers query-filter registration at app startup.

Why

• Single source of truth for "is this allowed?" — checks live next to the models, registry, and middleware that enforce them.
• No more per-view decorators — one URL-permission map replaces ~200 decorator lines scattered across 26 view files.
• Decouples dojo.models from authorization — RBAC models live in their own module, removing circular-import pressure.
• Pluggable — get_authorized_* falls back to unfiltered querysets when no RBAC backend is registered, so non-RBAC deployments keep working.

Behavioral changes

None intended. Authorization checks for the ~198 mapped URLs now run in middleware (process_view) instead of inside view bodies, but produce the same allow/deny outcome.

Test results

• Full Django unit-test suite (Rest Framework × 4 platform combos) — green.
• K8s deployment smoke (kubernetes 1.33.11, 1.35.4) — green.
• Full Selenium UI matrix — green.
• New unittests/test_permissions_audit.py exercises the URL-permission map for completeness.

Documentation

No external documentation impact — this is a structural / internal change.
