feat: Creation APIs for Programs, Opportunities, and related resources

[jjackson]

Product Description

Adds REST API endpoints to enable full end-to-end creation of Programs, ManagedOpportunities, PaymentUnits, DeliverUnits, and user invitations — filling the gap where these operations were previously only available through the web UI.

A new create OAuth scope gates all write endpoints. Read endpoints require only authentication (no scope), matching the existing OpportunityViewSet pattern.

Technical Summary

Jira: CCC-XXX (feature request for Connect team)
Draft PR: #1070

New Endpoints

Method	URL	Auth	Purpose
GET	/api/lookups/delivery_types/	IsAuthenticated	List delivery types
GET	/api/lookups/currencies/	IsAuthenticated	List currencies
GET	/api/lookups/countries/	IsAuthenticated	List countries
GET/POST	/api/program/	Read: IsAuth / Write: + create scope + PM admin	List/create programs
GET/POST	/api/program/<id>/opportunity/	Read: IsAuth / Write: + create scope + PM admin	List/create managed opportunities
GET/POST	/api/program/<id>/applications/	Read: IsAuth / Write: + create scope + PM admin	List/invite orgs to program
GET/POST/DELETE	/api/opportunity/<id>/payment_units/	Read: IsAuth / Write: + create scope + PM admin	CRUD payment units
GET/POST/DELETE	/api/opportunity/<id>/deliver_units/	Read: IsAuth / Write: + create scope + PM admin	CRUD deliver units
POST	/api/opportunity/<id>/invite/	create scope + PM admin	Invite users by phone number

Key Design Decisions

• OAuth scope: New create scope for writes only (mirrors export scope pattern). Reads require only IsAuthenticated, matching existing API convention.
• Permissions: IsOrgProgramManagerAdmin DRF permission class mirrors the existing org_program_manager_required decorator. For nested routes (under Program), initial() injects the PM org slug from the program for permission checking.
• Queryset scoping: All read querysets are scoped to the user's org memberships (direct org membership OR PM org via program), preventing cross-org data leakage.
• Program inheritance: ManagedOpportunity auto-inherits currency/country/delivery_type from parent Program.
• Response format: ReadSerializerResponseMixin ensures POST responses return the full read serializer (with id, UUID, slug, timestamps) instead of just echoing input fields.
• Validation: DeliverUnit validates that payment_unit belongs to the URL opportunity. InviteUsers checks has_ended before queueing.

New Files

commcare_connect/opportunity/api/permissions.py   - IsOrgProgramManagerAdmin permission class
commcare_connect/opportunity/api/lookups.py       - Lookup viewsets (DeliveryType, Currency, Country)
commcare_connect/program/api/__init__.py          - Package init
commcare_connect/program/api/serializers.py       - Program, ManagedOpp, ProgramApplication serializers
commcare_connect/program/api/views.py             - Program, ManagedOpp, ProgramApplication viewsets
commcare_connect/opportunity/tests/test_creation_api.py - 14 tests
commcare_connect/program/tests/test_creation_api.py     - 12 tests

Safety Story

• All write endpoints require both OAuth create scope AND org program manager admin role
• Read querysets scoped to user's org memberships (prevents cross-org enumeration)
• DeliverUnit validates payment_unit FK belongs to same opportunity (prevents cross-opp injection)
• InviteUsers checks opportunity.has_ended (returns 400 instead of silently queueing no-op)
• Non-existent program_id returns 404 (not confusing 403)
• 26 tests covering create, list, permission rejection, validation, and edge cases
• Full existing test suite (696 tests) passes with no regressions
• Stress tested locally against running dev server (full E2E flow)

QA Plan

• Verify OAuth token with create scope can access write endpoints
• Verify OAuth token without create scope gets 403 on writes but 200 on reads
• Verify non-PM org admin gets 403 on write endpoints
• Verify unauthenticated requests get 401
• Test full creation flow: Program -> ProgramApplication -> ManagedOpportunity -> PaymentUnit -> DeliverUnit -> Invite
• Verify POST responses include full read serializer (id, UUID, slug, timestamps)
• Verify invite to ended opportunity returns 400
• Verify cross-org queryset scoping (user from org A cannot read org B's resources)

Code review

Found 1 issue:

1. Read endpoints for nested resources (PaymentUnit, DeliverUnit, ManagedOpportunity, ProgramApplication) do not scope querysets to the user's organization membership. Any authenticated user who knows a valid opportunity_id or program_id UUID can enumerate resources belonging to other organizations. ProgramViewSet correctly filters by organization__memberships__user=self.request.user, but the nested viewsets do not apply equivalent filtering. Write operations are properly gated by IsOrgProgramManagerAdmin.
