Migrate IWF endpoint clients to account-scoped lambda with feature flag toggle

[Copilot]

Migrates reportToIWF and selfReportToIWF from ServerlessService.ts into a dedicated iwfService.ts, adding a use_twilio_lambda_for_iwf_reporting flag to route calls to either the legacy serverless endpoints or the new account-scoped lambda (/integrations/iwf/reportToIWF, /integrations/iwf/selfReportToIWF).

Description

Key changes

• FeatureFlags.ts — New flag use_twilio_lambda_for_iwf_reporting following the established use_twilio_lambda_* convention.
• iwfService.ts (new) — Houses reportToIWF and selfReportToIWF. When the flag is on, routes to the lambda endpoints with useTwilioLambda: true. Normalises the reportToIWF lambda response ({ status, data } wrapper → unwrap to data) so callers are unaffected. selfReportToIWF needs no normalisation — the lambda already returns { reportUrl, status } directly.
• ServerlessService.ts — IWF functions and their now-unused type imports removed.
• csamReportApi.ts — Import updated from ServerlessService → iwfService.
• csamReportApi.test.ts — Updated import and jest.mock references from ServerlessService to iwfService so the existing tests correctly mock the new service location.

// iwfService.ts (reportToIWF, abridged)
const useTwilioLambda = getAseloFeatureFlags().use_twilio_lambda_for_iwf_reporting;
const response = await fetchProtectedApi(
  useTwilioLambda ? '/integrations/iwf/reportToIWF' : '/reportToIWF',
  body,
  { useTwilioLambda },
);
return useTwilioLambda ? response.data : response;

Verification steps

1. Set use_twilio_lambda_for_iwf_reporting: false — confirm CSAM counsellor and child self-report flows hit the serverless endpoints as before.
2. Set use_twilio_lambda_for_iwf_reporting: true — confirm the same flows route to the account-scoped lambda (/integrations/iwf/reportToIWF, /integrations/iwf/selfReportToIWF) and complete successfully.

AFTER YOU MERGE

1. Cut a release tag using the Github workflow. Wait for it to complete and notify in the #aselo-deploys Slack channel.
2. Comment on the ticket with the release tag version AND any additional instructions required to configure an environment to test the changes.
3. Only then move the ticket into the QA column in JIRA

You are responsible for ensuring the above steps are completed. If you move a ticket into QA without advising what version to test, the QA team will assume the latest tag has the changes. If it does not, the following confusion is on you! :-P

<issue_title>Migrate client code calling IWF endpoints in plugin-hrm-form to call the versions in account-scoped lambda</issue_title>
<issue_description>## Description

• Create a feature flag to toggle whether to point to the legacy serverless endpoint or the new account-scoped lambda endpoint
• Update the code to use this flag to change the URL used in the http call to the /reportToIWF and /selfReportToIWF endpoints
• Migrate the clients from ServerlessService.ts to a new iwfService.ts file in the same directory

Additional context

The new endpoints are implemented in /lambda/account-scoped/integrations/iwf and routed to in /lambda/account-scoped/router.ts

Follow the same naming convention for the feature flags as other functionality being migrated to the account-scoped lambda, i.e. use_twilio_lambda_*</issue_description>

@copilot import references in the unit tests for the iwf endpoints are still pointing at their old location in ServerlessService.ts, causing them to fail

Update the import directives to point to the new location

Fixed in 5a534f1 — updated the import and jest.mock in csamReportApi.test.ts to point to '../../../services/iwfService' instead of '../../../services/ServerlessService'. All 42 tests pass.
