Description

This PR implements the Asterism service, including:

• getAsterismConsent
• setAsterismConsent
• getIsPnvrConstellationDevice

This PR uses gRPC proto definitions and client implementation introduced in play-services-constellation (PR #3359)

[chenlinxi890-spec]

Complementary PR submitted: #3596 (#3596)

This PR adds two critical bug fixes on top of the Constellation/Asterism implementation:

1. gRPC timeout fix: Added connectTimeout/writeTimeout/callTimeout (60s) — only readTimeout was set
2. DeadObjectException fix: Wrapped callbacks.onPhoneNumber* in try-catch

These address the bugs identified by unpluggederan in issue #2994 comments.

[chenlinxi890-spec]

Quick update: I submitted a complementary fix PR (#3596) but @mar-v-in correctly pointed out it duplicates #3360 since the timeout and callback fixes are already in this PR. Closing #3596.

The two critical bugs mentioned by @unpluggederan are already addressed:

1. ✅ gRPC timeout fix — commit 309566d (Set timeout on the right place)
2. ✅ DeadObjectException fix — commit 2ec6d36 (Wrap callbacks in try catch)

Remaining issue from @unpluggederan's last comment:

• Tachygram/DroidGuard attestation failures causing RCS to show 'Connected' but not actually work

I'm investigating this DroidGuard attestation path next.
