Organization settings, split into dedicated pages

Organization settings used to stack the organization profile, member management, and API keys on one scrolling page. They're now three separate pages (General, Members, and API keys) under a Settings sub-navigation, the same pattern already used for your personal account settings.

General (your organization's name and logo) stays at /dashboard/settings. Members moved to /dashboard/settings/members, and API keys to /dashboard/settings/api-keys.

The entry point moved too: Settings is no longer a link in the main sidebar. Open it from the organization switcher at the top of the sidebar, directly above Create organization.
