Highlight server-side validation as the primary way to validate the user input. Present client-side validation as a UX optimization. Provide a complete example for adding a custom validator (both server-side and client-side). Introduce JSR-380 instead of assuming readers know what it is. Make the example more realistic. Also update the docs after fixing vaadin/flow#8551 and vaadin/flow#8552 Fixes #1291 Fixes #1292
