Customer Feedback: Usability Issues in the Workflow notifications settings page

### Problem Statement

Feedback Provided by Customer:

1) The "Settings for Organization" heading confused me. Initially I thought it was a setting that affects all colleagues using Sentry and not a personal setting so I didn't want to change it. Looking more closely, I think this is in fact a personal setting (looking at the breadcrumb that includes the word "Account"). This could use a better label
2) Adding a project-specific setting requires pressing the purple "+" button (see screenshot). Initially I navigated away from this page without pressing the "+" button, since I thought this button was used to add another row to this table, when it's actually used to submit the current row. I'd recommend changing this to a verbal CTA like "Save", as well as preventing navigating away from the page if there's unsaved form data locally.

Start by locating the Workflow notifications settings page and reviewing the current “Settings for Organization” heading and purple “+” control described in the issue. Done means the personal-setting label is clearer, the project-specific action uses an explicit save CTA, and navigating away with unsaved form data is prevented.
