Role-based permissions DAP - Enable on projects permission check integration for custom flows
## Summary
This issue integrates DAP (Duo Agent Platform) role-based `Enable on projects` permission checks into custom flow enablement operations. It ensures that only users with appropriate permissions (maintainer+ by default) can enable or disable custom flows on projects.
## Background
As part of the DAP role-based permissions epic (#19743), we need to enforce the `Enable on projects` permission across all DAP flow enablement operations. Custom flows are a core DAP resource that requires proper access controls for project-level enablement.
The `Enable on projects` permission controls:
- **Enable**: Enabling custom flows on projects
- **Disable**: Disabling custom flows on projects
- **Toggle**: Toggling flow availability on projects
The `Enable on projects` permission is limited to maintainer+ roles by design. Flows can only be added to a project by a maintainer+.
## Requirements
### Permission Check Integration
- [ ] Identify all entry points for custom flow enablement operations on projects
- [ ] Integrate `DapPermissionService.can_user_perform_action?` checks for `:enable_on_projects` action
- [ ] Ensure permission checks occur before any enablement operation
- [ ] Handle permission denial gracefully with appropriate error messages
- [ ] Enforce maintainer+ minimum role requirement
### Enablement Operations to Protect
#### Enable Operations
- [ ] Enabling custom flows on projects via UI
- [ ] Enabling custom flows on projects via API/GraphQL
- [ ] Bulk enable operations
#### Disable Operations
- [ ] Disabling custom flows on projects via UI
- [ ] Disabling custom flows on projects via API/GraphQL
- [ ] Bulk disable operations
#### Toggle Operations
- [ ] Toggling flow availability on projects
### Service Account Considerations
Each flow has a service account assigned (see epic #19478). Enablement operations should consider:
- Service account can only be added by an owner+ to a top-level namespace
- Flow can only be added to a project by a maintainer+
- Changing flow service account requires appropriate permissions
## Technical Implementation
### Locations to Update
Based on the codebase analysis, identify and update all locations where custom flows are enabled on projects. This may include:
- Flow enablement controllers
- GraphQL mutations for flow enablement operations
- API endpoints for flow enablement
- Project settings interfaces for flow configuration
- Bulk operation handlers
- Flow import/export functionality
### Permission Check Pattern
```ruby
# Before any enable operation on custom flow for project
unless DapPermissionService.can_user_perform_action?(current_user, namespace, :enable_on_projects)
return error_response('Insufficient permissions to enable custom flows on projects. Maintainer role or higher required.')
end
# Perform enablement operation
perform_flow_enablement_operation(flow, project, params)
```
## Acceptance Criteria
- [ ] All custom flow enablement operations have permission checks
- [ ] Users without `Enable on projects` permission receive clear error messages
- [ ] Error messages indicate maintainer+ role requirement
- [ ] Permission checks are performant (use caching from DapPermissionService)
- [ ] UI elements for enablement are hidden/disabled for users without permission
- [ ] Integration tests verify permission enforcement
- [ ] Tests cover both allowed and denied scenarios
- [ ] Audit logging captures enablement operations and permission checks
## Testing Scenarios
- [ ] User with maintainer role can enable custom flows on projects (default config)
- [ ] User with owner role can enable custom flows on projects (default config)
- [ ] User with developer role cannot enable custom flows on projects
- [ ] User with reporter role cannot enable custom flows on projects
- [ ] Custom permission configuration is respected (maintainer+ only)
- [ ] Instance-level and namespace-level permissions work correctly
- [ ] All enablement operations (enable, disable, toggle) respect permissions
- [ ] Bulk operations respect permissions
- [ ] UI appropriately reflects permission state
- [ ] Flow can only be added to project by maintainer+
## User Experience
- [ ] Enablement UI elements are hidden for users without permission
- [ ] Clear messaging when users attempt unauthorized operations
- [ ] Guidance on how to request access or who can perform operations
- [ ] Consistent permission enforcement across UI, API, and GraphQL

## Notes
The `Enable on projects` permission for custom flows is an important security control. Only maintainer+ users should be able to enable flows on projects, as these can execute code and access resources within projects. The restriction that flows can only be added to a project by maintainer+ is an important security boundary.
