chore: migrate workspace to Nx 23.1

Squash of the Nx 23.1 migration commits:
- checkpoint before running migrations (dependency updates)
- 23-0-0-add-migrate-runs-to-git-ignore
- change-detection-eager
- http-xhr-backend
- strict-templates-default
- strict-safe-navigation-narrow
- update-23-1-0-convert-to-flat-config
- update-23-1-0-remove-conflicting-extended-diagnostics

Instead of keeping the 23-1-0-add-ignore-deprecations-for-ts6 migration's
"ignoreDeprecations": "6.0" suppressions, the TS6-deprecated options are
fixed directly: baseUrl removed (paths made explicitly relative),
tools target bumped es5 -> es2022, and the esModuleInterop: false pin
dropped in favor of the TS6 default.

The generated migrations.json and tools/ai-migrations docs are not kept.
