update bridge-task image URL after GitHub org rename

[jgrant-sms]

Summary

The hardcoded bridge-task container image URL references the old GitHub organization (sst/sst), which is no longer accessible after the org was renamed to anomalyco.

Problem

ECS tasks fail in dev mode because the image at ghcr.io/sst/sst/bridge-task:20241224005724 returns "denied".

Solution

Update references from ghcr.io/sst/sst/bridge-task to ghcr.io/anomalyco/sst/bridge-task in:

• platform/src/components/aws/task.ts (runtime image reference)
• platform/scripts/build (build/push target)

Verification

# New location - accessible
docker manifest inspect ghcr.io/anomalyco/sst/bridge-task:20241224005724

# Old location - denied
docker manifest inspect ghcr.io/sst/sst/bridge-task:20241224005724
