build(angular): upgrade to angular 22, add to-be-played project

Move to Angular 22 and update all dependencies. TypeScript stays on 6.0
(7 is blocked by Angular 22). Drop the ip-address override, add
fast-uri and basic-ftp overrides for audit fixes.
Set ChangeDetectionStrategy.Eager on components, as the ng update
migration does, and turn off the new OnPush lint rule.
Add the To Be Played project to the projects page and the about page.
