Add map summary screen (place count + Start button) before the guide

After resolving location, the map screen now checks how many places
are nearby (same server-side iterative radius expansion the guide
screen uses) and shows "Found N places within Rm" with a Start button,
instead of jumping straight into narration. The search cap is raised
to 10km (was 5km) — if nothing turns up within that, a "nothing found"
message is shown instead.

This also addresses a UX report: the guide screen's Tinder-style card
stack only shows one card at a time by design, which read as "it only
found one place" even when 5 were actually there. Added a "1 / 5"
position indicator to the card stack so it's clear there's more to
swipe through, and the new summary screen surfaces the real count
upfront regardless.

Verified: ./gradlew testDebugUnitTest passes, :app:assembleDebug
produces a working APK, sent to Telegram.
