fix: run IML function tests against draft code, not published code

[Kateřina Beňová (KatBen-Make)]

JIRA: https://make.atlassian.net/browse/IEN-14781
The function test runner was fetching all function code via the listing endpoint (/functions?code=true), which returns the published version. Now fetches each function's code via its direct endpoint (/functions/{name}/code) to get the latest draft, matching how test code is already fetched.

Summary:

• Bug: Running IML function tests (F6 / "Run IML test") on a published app used the published (compiled) function code instead of the latest draft. Edits to code.js were not reflected when running tests until the app was re-published.
• Root cause: The test runner fetched function code via the listing endpoint (GET /functions?code=true), which returns the published code property. The test code was correctly fetched via its direct endpoint.
• Fix: Fetch each function's code individually via GET /functions/{name}/code (the direct draft endpoint), matching how test code is already fetched.

Test plan:

• Open an already-published app with custom IML functions

• Edit a function's code.js (e.g. change the return value)

• Save the change (sends it to server as draft)

• Run "Run IML test" (F6) — verify the test runs against the updated code, not the old published version

• Verify tests still pass for unpublished (new) apps as before

Pull request overview

Updates the IML function test runner to execute against the latest draft function code by fetching each function’s code from its direct endpoint instead of using the listing endpoint that returns the published version.

Changes:

• Fetches function names via the listing endpoint and then fetches each function’s draft code via /functions/{name}/code.
• Runs test-code fetch and function-list fetch in parallel.
• Bumps package version to 2.5.1.
