fix(site): Phone chip, Free forever Cost copy, and privacy GA disclosure (#868)

* fix(site): align Phone chip, Cost copy, and privacy with GA

Use the official Android beta / iOS TestFlight chip on #ecosystem.
Replace Free forever with Free and open source on privacy and open-source.
Disclose vocalinux.com Google Analytics and scope no-telemetry claims to the installed app.

Fixes #867

* fix(site): make privacy GA disclosure match the live gtag

Spell out page views, the client-ID cookie, and IP/device processing for
G-7NBBNJNNQ7. Align Data Collection with PRODUCT.md, drop the hidden
telemetry weasel, and correct config.json plus the voice-storage row.
