Fix E2E tests broken by redesigned navigation menu (#18315)

## Summary
- **Settings selector**: The Settings navigation item is now rendered as
a `<button>` (via `NavigationDrawerItem` with `onClick`) instead of an
`<a>` link (with `to`). Updated `leftMenu.ts` POM and
`create-kanban-view.spec.ts` to use `getByRole('button', { name:
'Settings' })`.
- **create-record URL field**: The Linkedin field interaction was
missing an initial label click to trigger the hover portal rendering.
Added `recordFieldList.getByText('Linkedin').first().click()` before the
value click, matching the pattern used by the working Emails field.

## Test plan
- [ ] E2E `signup_invite_email.spec.ts` passes (uses
`leftMenu.goToSettings()`)
- [ ] E2E `create-kanban-view.spec.ts` passes (uses Settings click
directly)
- [ ] E2E `create-record.spec.ts` passes (Linkedin URL field
interaction)
- [ ] Existing passing E2E tests remain green
