Description

Fixes the translucent drawer sheet that stays painted from about a third of the way down the home screen after opening and closing All Apps (seen on the Pixel 7 Pro on ExpressiveOS with launcher 5.0.8, "Bottom sheet drawer" on, Android 17 base, not QPR2, so frosted glass is not involved).

Two things combine:

1. Turning on Bottom sheet drawer only recreated the activity. The device profiles were never rebuilt, so they kept the full-screen values (allAppsShiftRange 300 dp, allAppsPadding.top 0, bottomSheetDepth 0) while Flags.allAppsSheetForHandheld() answered true. The closed drawer therefore parks 300 dp down instead of off screen. The same stale-profile case happens when the process is started before unlock for TouchInteractionService, since the flag supplier is only installed on unlock.
2. AllAppsTransitionController.setAlphas runs while the state is still ALL_APPS, so it keeps the drawer as the scrim's drawing controller through the close animation, and nothing clears it afterwards. drawOnScrimWithScaleAndBottomOffset then keeps painting the sheet at the closed offset until some later state change happens to call setAlphas again. With a full-screen shift range the sheet is off screen so this was invisible before.

Changes:

• PreferenceManager2: the sheet preference calls reloadHelper.restart() (grid rebuild + recreate) instead of recreate().
• LawnchairApp.onUserUnlocked: when the sheet is on, rebuild the profiles once the flag supplier is installed.
• AllAppsTransitionController: after a transition out of ALL_APPS completes, drop the scrim's drawing controller.

Evidence from the phone: dumpsys activity top showed bottom_sheet_background VISIBLE (sheet mode) next to allAppsShiftRange: 1050.0px (300.0dp) and allAppsPadding.top: 0 (full-screen profile), state Normal, apps_view GONE, scrim still drawing. 1050 px is exactly where the ghost starts on the 3120 px screen.

Reasoning

The drawer sheet is drawn on the scrim, not on the apps view, so the apps view going GONE does not hide it. Keeping the scrim's drawing controller after the close is harmless only while the closed translation pushes the sheet off screen; the stale device profile broke that assumption. Both halves are fixed so neither can bring the ghost back on its own.

Testing

Not run on a phone yet (no local Gradle here; CI compiles). Steps for the 7 Pro:

1. Launcher settings > App drawer > Bottom sheet drawer: toggle it off and on. The drawer should relayout (content under the handle) without the activity-only recreate.
2. Open All Apps, close it, repeat three times, then press Home. No sheet should remain on the home screen. adb shell dumpsys activity top | grep -E "allAppsShiftRange|allAppsPadding.top" should show the sheet profile values (shift range near screen height, top padding non-zero) while the toggle is on.
3. Reboot with the toggle on; repeat step 2 (covers the pre-unlock profile build).
4. Toggle off: the drawer is full screen again and the dump shows 300 dp shift range.

CI: check-style is red here, but not because of this PR. spotlessKotlinCheck fails on the same 64 files (5 listed + "59 other files") as on the base branch's last PR (#45, run 41269970272, job 124740548400): ExpressiveCore.kt, FeedBridge.kt, AllAppsSearchInput.kt, SearchItemBackground.kt, AllAppsCategoryTabs.kt, ... none of which this PR touches, and the count did not grow. That spotless debt predates this branch (same on #43 and #44) and needs its own spotlessApply pass; not widening this PR for it.
