Migrate routing layer from deprecated kadira packages to modern alternatives

- Remove deprecated kadira:flow-router, kadira:blaze-layout, arillo:flow-router-helpers
- Add ostrio:flow-router-extra (modern, actively maintained)
- Add pwix:blaze-layout (maintained fork of kadira:blaze-layout)
- Convert all 22 BlazeLayout.render() calls to this.render() in route actions
- Maintain full backward compatibility with existing FlowRouter API
- All route definitions remain functional without syntax changes
- Build compilation succeeds without errors

This migration prepares Wekan for Meteor 3.0 compatibility by replacing
9-year-old deprecated routing packages with modern alternatives.

Next phase: Schema and async collection methods migration
