fix(permissions): v0.5.1 — bug fixes, i18n, and cleanup

[edimedia]

Bug fixes:

• E007: replace 'group' (singular) with 'groups' (plural) across checks, utils, and docstrings to match presets.py v0.5.0 format
• E022: fix false positives on scope ownership — only check conflicts between discovered app presets, not the already-merged base preset
• any_permission_check(), allowed_for(), denied_for(): add missing is_active=True filter so deactivated grants are properly ignored
• authorization.py: use getattr(settings, 'ACCESS_MANAGER_SCOPE', 'access') to prevent AttributeError when setting is absent

Internationalization:

• Translate all exception messages from French to English using _('...').format(...) syntax for proper gettext support
• Update French .po translations — remove fuzzy markers, fill missing entries, fix python-brace-format placeholders

Cleanup:

• Remove pagination module (CursorPagination) — controllers already use Django Ninja Extra's PageNumberPaginationExtra
• Fix variable shadowing (roles -> role_objs) in update_group()
• Remove dead 'scopes' key from load_preset docstring
