Show the next alarm 24 hours ahead, not 8

An alarm set for the next morning left the dynamic zone before it was visible:
at 22:00 an alarm at 06:00 is eight hours away, so the part only appeared while
the phone was unlikely to be looked at. The window is now 24 hours, and the
setting summary says so (also in Danish; the other translations still say 8 and
will follow upstream).

Verified on the Titan 2 that Chrono (com.vicolo.chrono) registers its alarms the
way this part reads them: dumpsys alarm lists them as "Alarm clock" entries with
a showIntent pointing at Chrono, and AlarmManager.nextAlarmClock returns the
earliest one, so ACTION_NEXT_ALARM_CLOCK_CHANGED keeps the part up to date.
Tapping it opens Chrono as well - SHOW_ALARMS, SET_ALARM and SHOW_TIMERS all
resolve to com.vicolo.chrono/.MainActivity.

+## The clock widget's dynamic zone (agenda part and multiple slots)
+
+Upstream's home-screen clock has one "dynamic zone" below (or beside) the clock. Every enabled
+*part* (`DatePartProvider`, `MusicPartProvider`, `BatteryPartProvider`, `AlarmPartProvider`) reports
+a `getRanking()`; only the single highest-ranked part with a ranking above zero is shown. Two
+changes on top of that:
+
+* **The zone can show more than one part.** The setting `clockWidgetDynamicZoneSlots` (1..number of
+  enabled parts) caps how many of the highest-ranked parts are rendered;
+  `ClockWidgetVM.getActiveParts()` returns that sorted list instead of a single provider. The
+  slider lives in `ConfigureClockWidgetSheet` next to the part toggles.
+* **A new part shows today's agenda.** `CalendarPartProvider`
+  (`app/ui/.../widgets/clock/parts/`) is toggled with the *Events* switch
+  (`clockWidgetCalendarPart`). It lists the events that are still running or upcoming today, plus
+  today's all-day events, capped at 4 rows — if there are more, the last row is a "+N more events"
+  hint that opens the calendar app. Tapping a row opens the event
+  (`CalendarEvent.launch`, i.e. `ACTION_VIEW` on `content://com.android.calendar/events/<id>`,
+  which KashCal handles). Rows reuse `CalendarEvent.getSummary()` from
+  `ui/launcher/search/calendar/CalendarItem.kt` (made `internal` for this), so an all-day event
+  reads "All day" and a timed one reads e.g. "09:00 – 09:30".
+
+Rankings, in the order the zone prefers them: `CalendarPartProvider` 70 when an event is running or
+starts within 30 minutes, else 30 while there are events left today, else 0 (so the date part keeps
+the slot on an empty day); alarms 60 (ringing within 8 h); media 80 while playing; battery 55 when
+low and 10 when charging or set to "always"; date 1. Tasks (`CalendarEvent.isTask`) are filtered out
+of the agenda; a tasks part is planned but not implemented.
+
+`CalendarPartProvider` keeps itself up to date with a `ContentObserver` on
+`CalendarContract.Events.CONTENT_URI` plus a 15-minute ticker (the other calendar consumers in the
+launcher only re-query when they become visible). `PartProvider.setTime()` is called every second
+by the clock widget; the provider folds that into its ranking instead of re-querying.
+
+The clock settings themselves are in `core/preferences`: `LauncherSettingsData` (new fields
+`clockWidgetCalendarPart`, `clockWidgetDynamicZoneSlots`), `ClockWidgetParts` and the
+`ClockWidgetSettings` accessors in `core/preferences/.../ui/ClockWidgetSettings.kt`, and the UI
+state in `ui/settings/clockwidget/ClockWidgetSettingsScreenVM.kt`. New strings are English-only in
+`core/i18n/src/main/res/values/strings.xml`; translations come from Crowdin upstream.

+`~/android-keystores/` in the Termux home.
+
+### Building on the phone itself (Termux)
+
+The phone builds this project without a desktop. `scripts/ondevice.sh` wraps the loop:
+
+    scripts/ondevice.sh build      # assemble the debug APK
+    scripts/ondevice.sh install    # build, then pm install it (root)
+    scripts/ondevice.sh start      # launch the debug build
+    scripts/ondevice.sh logs       # follow logcat of the debug build (Ctrl-C to stop)
+    scripts/ondevice.sh crash      # newest crash report for the debug build
+    scripts/ondevice.sh release    # assemble the signed release APK
+
+Or call Gradle directly: `./gradlew :app:app:assembleDefaultDebug`. A full build takes about 13
+minutes (984 tasks), later ones 20-30 seconds; the release build (R8 plus `lintVital`) takes about
+11 minutes. Run `termux-wake-lock` first so the screen lock does not throttle it.
+
+The **debug** build is `de.mm20.launcher2.debug` (`isDebuggable`, its own empty data directory),
+so it installs next to the real launcher and can be logged with
+`su -c 'logcat --pid=$(pidof de.mm20.launcher2.debug)'`. Installing, reinstalling or uninstalling
+that package cannot affect the real launcher: different package, different data directory.
+
+> **Never uninstall `de.mm20.launcher2.release`.** It is the launcher the phone actually runs, and
+> the config (widgets, pages, tags, search settings) lives in its data directory
+> `/data/user/0/de.mm20.launcher2.release`, mostly under `files/datastore`. `pm install -r` of a
+> build signed with the same key keeps that data, but it does replace the running launcher, so do it
+> deliberately, after backing the data directory up. Reinstalling the *debug* build is always the
+> safe way to try a change.
+
+To try a fix in the real launcher with the real data, build the release APK and `pm install -r` it:
+same package (`de.mm20.launcher2.release`) and same key, so it replaces the installed build in
+place. The release APK is minified by R8, so this is the slow build. `scripts/ondevice.sh release`
+only *builds* it; it never installs anything.
+
+#### The SDK on the phone
+
+`~/android-sdk` (see `~/CLAUDE.md`) provides everything Gradle needs:
+
+* `platforms/android-37.0` — the compileSdk 37 platform, installed with `sdkmanager`.
+* `build-tools/36.0.0` — the version AGP 9.3.1 defaults to. Google only ships x86_64 build-tools,
+  so the three native tools are symlinks into `build-tools/34.0.4`, which is AndroidIDE's aarch64
+  build of the AOSP tools: `aapt2`, `zipalign` and `aidl`. Everything else in build-tools
+  (`d8`, `apksigner`, jars) is Java and runs as is.
+* `~/.gradle/gradle.properties` points `android.aapt2FromMavenOverride` at Termux's own aarch64
+  `aapt2` (2.20, newer than 34.0.4's) and lowers the Gradle/Kotlin daemon heaps to fit the phone.
+* `local.properties` in the repo root sets `sdk.dir`; it is git-ignored. The SDK itself is
+  machine-wide, not project-specific: another project just needs `termux-sdk init <repo>`, and
+  `termux-sdk install "platforms;android-35" "build-tools;35.0.0"` adds other SDK versions (it
+  patches their x86_64 native tools to aarch64, which plain `sdkmanager` cannot do). See
+  `~/CLAUDE.md` for what does and does not build on this phone.
