Switch all ecosystems to a weekly schedule and drop the redundant
patterns: ["*"] selectors. Remove the major group so patch+minor bumps
stay grouped into one PR per ecosystem while each major lands as its own
PR, matching the org standard.
Add npm coverage for the JS/TS surface (root, /infra CDK, /tests/e2e
Playwright, /ui dashboard) and assign updates to amoussa1229. Delete the
stale ui/yarn.lock so Dependabot tracks ui/bun.lock cleanly.
