Example: add sandbox buttons for trackConversion smoke testing

Adds two buttons on the main screen — "Track Pageview (sandbox)" and
"Track Conversion (sandbox)" — that fire against the
`sandbox.joshhanson.io` apikey on a shared test URL. The pageview lets
a session accrue history before the conversion fires so the conversions
topology has something to attribute to.

NOTE: the example app initializes the SDK with `dryRun=true`, which
suppresses real network sends. To exercise these buttons end-to-end
against mobileproxy, temporarily flip the fourth argument of
`ParselyTracker.init(...)` to `false`.

Used during the manual end-to-end verification of trackConversion on
the Android emulator: with logcat filtered to `Parsely:V`, confirm the
emitted "POST Data {...}" JSON includes `action: "conversion"` and the
`_conversion_type` / `_conversion_label` keys, then watch
dash.parsely.com for the conversion in the conversions report.
