fix(settings): lock site context to current URL, rename Workspace to Organization

- Site context is locked to the site from the current URL — no dropdown
  switcher. If not on a site page, defaults to Organization context.
- Renamed "Workspace" to "Organization" in all user-facing text.
- Removed unused CaretDown import and dropdown state.
