fix(automation,webui): grace-period cleanup and accent color persistence

cleanup_dead_apps was immediately removing packages invisible to
pm list (HMA filtering, multi-user, transient during updates).
Now checks /data/data/<pkg> and requires 3 consecutive misses.

WebUI accent picker didn't disable randomization on manual pick,
so the choice was overwritten on next page load. Also made the
target.txt save atomic (tmp+mv) to prevent daemon truncation race.

+## v5.27.0 (2026-03-18)
+
+### Bug Fixes
+- **Accent color not persisting** — manually picking an accent color from the picker didn't disable randomization, so the next page load or tab switch would randomize over the user's choice. Picker now auto-disables randomization and syncs the toggle state
+- **Apps silently removed from target.txt** — `cleanup_dead_apps` relied solely on `pm list packages -3` which can be filtered by HideMyAppList or miss apps in other user profiles. Now cross-checks `/data/data/<pkg>` existence and requires 3 consecutive misses before removing, preventing false removals during app updates or when HMA is active
+- **WebUI save race with daemon** — `target.txt` was written non-atomically (`echo > file`), allowing the daemon to read a truncated file mid-write. Now uses temp-file-then-rename
