- Update all updateable dependencies
- Add a few more unupgradable ones to updates blocklist
- Adapt to breaking changes
- Update to typescript 5.8, enable `erasableSyntaxOnly` which
necessitated a change because of forbidden syntax
- Misc cleanups
- Tested htmx, easymde, swagger, chart.js
- Update all JS and PY dependencies
- Tested affected dependencies
- Disabled `async-preventdefault` lint rule because it brought up new
false-positives.
In preparation for migrating to eslint flat config, move the config file
to javascript. Additional changes:
- `no-undef` is now disabled as it's no longer needed with typescript
- `no-restricted-globals` config is simplified
