feat(surveys): auto-submit rating and single-choice selections

[lucasheriques]

💡 Motivation and Context

Honor skipSubmitButton in Android Compose surveys, moving toward survey feature parity across all PostHog SDKs, with posthog-js as the reference. Eligible selections submit through the existing response/navigation callback without an extra tap.

Question	skipSubmitButton: true	False or absent
Numeric/emoji rating	Submit on selection	Explicit submit
Single choice without an open option	Submit on selection	Explicit submit
Single choice with an open option	Explicit submit	Explicit submit
Multiple choice	Explicit submit	Explicit submit

The raw flag is exposed to custom renderers and defaults to false. Each selection forwards its answer once; the next question starts without the previous selection. Existing JVM display-question constructor signatures are preserved.

Partial-response collection and persistent resume are covered separately in #768.

Review path

1. Interaction tests: real taps, button visibility, answer values and next-question state.
2. Raw question and display models: flag propagation and constructor compatibility.
3. SurveySheet and choice eligibility: submission and manual fallback.

💚 How did you test it?

Passed: make testSurveyUI (27 Compose tests, including 10 mounted cases), CI=true make compile, formatting checks and CodeScene. Tests cover decoding/mapping, eligible/manual paths, open-choice text, returned branching destinations and exact answer sequences. Disabling auto-submit callbacks made the eligible interaction cases fail.

Tests mount the real Compose sheet in Robolectric with a response recorder. Before combining with #768, reconcile Makefile/CI conflicts and test auto-submit through persistent resume and partial-event capture together.

Sample app screenshots

Captured from this PR's SDK (bd4008e) running in the sample app on Pixel 7 emulator, Android 16 / API 36. A local HTTP fixture supplies the survey; SDK fetching, event targeting and native presentation run through the normal app integration.

Rating: no submit button	After tapping 4: next question	Other: explicit submit

Tapping 4, then Easy to use, advanced without a submit tap. Entering Better search under Other required Submit; the local receiver recorded one survey sent event with all three answers.

📝 Checklist

### Issue 1
posthog-android-surveys-compose/src/test/java/com/posthog/android/surveys/compose/internal/ui/SurveyAutoSubmitTest.kt:17-28
**Renderer behavior remains untested**

This parameterized test only checks the `shouldAutoSubmit` eligibility rule. It does not render or interact with `SurveySheet`, so regressions where selecting an eligible rating or choice fails to submit exactly once, advance the survey, or hide the submit button would pass this suite. Adding an interaction test for that new flow would close this non-blocking coverage gap.
