This change updates the _Essentials_ topic with the following changes: * Change the "Managing dynamic data" topic to "Reactivity with signals", largely replacing the existing content to focus specifically on signals. * Replace the "to-do" examples with examples for building a `UserProfile` component. I made this change because the todo-item component had an accessibility problem: it was a list item component that rendered an `li` into its own template. This meant that the component's host element was in between the `ul` and the `li`, which is invalid. The "right" way to do this would have been to use a component with an attribute selector, but this isn't something that fits into the _Essentials_ guide. * Reorder some of the concepts in the components topic * Combine "Rendering dynamic templates", "Conditionals and loops", and "Handling user interaction" into one topic, "Dynamic interfaces with templates". Having these as separate topics meant that there was more preamble/scaffolding around these relatively straightforward ideas. * Renamed the "Sharing logic" topic to "Modular design with dependency injection". Aside from this, I have made no meaningful changes to the DI topic; I may come back for another edit pass here, but this is not necesary for v19. * Add a link to the in-depth guide for each essentials topic. * Add a new introduction to the _Essentials_ overview that explains what this guide is and what it's trying to accomplish.
