Fix extended-typeorm ESM imports

[phroi]

Why

• Make @rosen-bridge/extended-typeorm load correctly under native Node 22 ESM resolution.
• Keep CLI Docker examples aligned with the Rosen Node 22 baseline.

Changes

• Add .js specifiers to relative runtime imports in extended-typeorm TypeScript source.
• Add a changeset for the ESM import fix.
• Update CLI README Docker examples from Node 20.11 to Node 22.18.0.

Dependency Notes

This package-level ESM fix is independent from the notification package fix, but both should be published before the watcher Node 22 release.
