fix(backend-api7): include plugins when dumping stream_route

[AlinsRan]

Problem

ToADC.transformStreamRoute (the dump / read direction) drops the plugins
field, while FromADC.transformStreamRoute (the write direction) keeps it.
So dumping a stream route from the API7 backend always returns it without
plugins.

The differ relies on the dumped remote state to know the current plugins. With
plugins missing from the dump:

• Adding plugins is detected (local has them, remote appears empty) ✓
• Removing the last plugins is not detected (local empty == remote
  empty), so stale stream-route plugins are left on the gateway ✗

Fix

Map plugins in ToADC.transformStreamRoute, mirroring transformRoute and
the write-direction FromADC.transformStreamRoute.

Verification

Added libs/backend-api7/test/transformer.spec.ts. Confirmed by running it both
ways:

• without the fix: ToADC.transformStreamRoute preserves plugins fails
  (Received: undefined)
• with the fix: passes

Full backend-api7 (20) and differ (31) unit suites pass.

Summary by CodeRabbit

• Bug Fixes

  • Fixed loss of stream route plugins during transformation so plugin configurations are preserved.

• Tests

  • Added unit tests to cover stream route plugin round-trips and prevent regressions.
  • Added end-to-end tests validating plugin lifecycle (sync, dump, removal, delete).

📝 Walkthrough

Walkthrough

ToADC.transformStreamRoute now preserves the plugins field when converting stream routes; unit tests and an end-to-end spec validate plugin persistence, removal, and dump round-trips.

Changes

Stream Route Plugins Fix

Layer / File(s)	Summary
Transformer passthrough implementation libs/backend-api7/src/transformer.ts	ToADC.transformStreamRoute now includes route.plugins in the returned ADCSDK.StreamRoute.
Transformer unit tests libs/backend-api7/test/transformer.spec.ts	Adds tests asserting FromADC.transformStreamRoute and ToADC.transformStreamRoute preserve plugins, including a regression case preventing plugin loss.
E2E plugin lifecycle test libs/backend-api7/e2e/stream-route-plugins.e2e-spec.ts	New Jest E2E spec that syncs a stream service/route with an ip-restriction plugin, verifies dump preserves plugins, removes plugins and verifies dump reflects removal, then deletes resources.
