✨ Capture page URL in all JS client SDKs (#220)

## Summary

Sends the current page URL as a `url` property when capturing
screenshots. This enables the backend to link individual screenshots to
their corresponding deploy preview pages (preview-to-screenshot
integration).

- **Static Site**: `properties.url = page.url()` — Playwright page
available in `captureAndSendScreenshot`
- **Storybook**: `{ properties: { url: page.url() } }` passed to
`vizzlyScreenshot` — was previously sending no properties
- **Vitest**: `url: page.url()` added to the properties object built in
`toMatchScreenshot`
- **Ember**: `url: window.location.href` added to browser-side
properties payload — screenshot server forwards as-is

All placed before the user's `...customProperties` spread so users can
override if needed.

## Test plan

- [x] `npm test` — 1892 pass, 0 fail
- [x] `npm run lint` — clean
- [x] Storybook screenshot test mocks updated with `url()` method
- [ ] Deploy and verify `url` appears in screenshot records via Vizzly
dashboard
