fix(miniapp): preserve package version on install

[bobleer]

Summary

• preserve the version declared in validated MiniApp packages during first install
• rebuild runtime revision state after applying the package version so UI metadata and runtime invalidation stay consistent
• cover both direct .bfminiapp imports and marketplace installs with regression tests

Root cause

The strict package installer discarded MarketPackageMeta.version and delegated to the normal create path, which always initializes a MiniApp at version 1. The installed gallery then correctly rendered that incorrect persisted value.

Testing

• cargo test -p bitfun-product-domains --features miniapp miniapp::runtime_facade::tests -- --nocapture
• cargo test -p bitfun-product-domains --features product-full
• node scripts/check-core-boundaries.mjs
• git diff --check

AI-assisted change; fully tested at the product-domain contract boundary.
