Apps sharing a UID are controlled together by the VPN (blocking is
per-UID), so changing a setting for one app silently affects its
shared-UID siblings. Surface this instead of hiding it:
- Details screen now shows the app's UID and, if other installed
packages share it, their names ("Shares app ID with: ...").
- App-list search supports "uid:<number>" to find every app sharing
a given UID.

There was a problem hiding this comment.
Reviewed the UID display, shared-package lookup, uid: filter behavior, layout integration, and surrounding details/search code. I found no actionable correctness issue. :app:compileGithubDebugJavaWithJavac succeeds, and the branch is clean.

Summary
Closes #229.
Android apps can share a UID (e.g. via
android:sharedUserId, or when thesystem assigns the same UID to multiple packages). TrackerControl's
blocking is applied per-UID, so a setting change for one app silently
affects its shared-UID siblings — several users found this surprising,
and one commenter specifically asked for visibility into this without
adding UI clutter or new toggles.
This PR adds minimal, unobtrusive visibility into UID sharing:
DetailsActivity): shows the app's UID under thetoolbar, and — only if other installed packages share that UID — a
second line "Shares app ID with: ..." listing them, using
PackageManager.getPackagesForUid.AdapterRule'sFilter): supports auid:<number>query to filter the list down to every app sharing a given UID, so users
can go find the siblings mentioned in the details screen. Existing
free-text/UID search behavior is unchanged.
app_uid,app_uid_shared_with) added to the baseEnglish
strings.xmlonly, per the project's translation workflow.No new settings/toggles were added, keeping the UI as simple as before.
Test plan
./gradlew :app:compileGithubDebugJavaWithJavacpasses.screen and confirm the UID line appears (and the "shares app ID
with" line appears for an app that has a shared-UID sibling, e.g.
two apps from the same vendor using
android:sharedUserId).search
uid:<uid>for a known UID and confirm only apps with thatUID are shown.
