Fix RequestBlocklistTest on native input builds

The Internal Privacy Tests job runs RequestBlocklistTest on the
internal build, where native input is now enabled by default
(#8588). With native input on, the omnibar disables the legacy
omnibarTextInput and routes taps through a click-catcher overlay,
so Espresso's typeText() failed with a PerformException on the
disabled, input-connection-less view.

Drive the unified input flow instead: after the warm-up page
loads, tap the omnibar click-catcher to open the input screen and
type the URL into the native inputField, mirroring the e2e tests.
Loading the warm-up page first also gives the privacy config time
to load before the request-blocklist page fires its requests,
which avoids a content-level race that a direct page load hit.

Verified on a Pixel 8 Pro emulator (API 34, same level as CI):
the test passes 4/4 runs.
