fix(phone-connect): zh-Hans locale, aliasMap, box padding, volume, config data loss, interval, dead settings, slider, UI issues (#199)

* fix(phone-connect): zh-Hans locale, switcher aliasMap, box padding

- Rename zh_hans -> zh-Hans (plugin.toml value, en.json key) and add
  the missing translations/zh-Hans.json. The zh_hans tag does not match
  BCP 47, so the framework's materialize step dropped the Chinese
  translation file and t() returned raw dot keys in the UI.
- Add missing aliasMap definition in switcher() so the multi-device
  panel no longer errors on aliasMap[id]. Fixes #176.
- Replace ui.box({padding=...}) with ui.row({padding=...}); box does
  not support the padding prop, causing ui-tree warnings on open.

Supersedes #190 (which covers only the aliasMap fix).

* fix(phone-connect): volume quoting, config data loss, interval, dead settings, slider, UI issues

1. media_set_volume: shellQuote the <int32> variant arg (was unquoted,
   shell treated < as redirect; same fix as media_seek).
2. onConfigChanged: track last-applied custom_image/device_alias values
   so unrelated config edits (e.g. language switch) no longer wipe a
   device's image/alias. Seed trackers at init so reload is safe too.
3. state_update_interval=0: return 3600000ms + guard in update() to
   skip auto-refresh, matching the '0 disables' description.
4. Remove 4 dead settings (show_ongoing_media, show_device_placeholder,
   scan_subdirectories, max_recent_images) declared but never read,
   plus orphan recent_images translation keys.
5. Media slider: freeze value during drag via per-device dragState so
   the 1s service refresh doesn't yank the slider back. Also fixes
   onDragEnd seeking to a stale seekPos.
6. Minor: runCli reports cli_failed not no_backend; browse uses runAsync
   not runInTerminal; charging color priority over low-battery; device
   name falls back to d.name; fix comment mismatches.

* chore: bump version to 0.1.1

* fix: use lowercase zh-hans translation key to pass CI validation

CI rejects uppercase in translation keys (zh-Hans). The translation key
and label_key are now lowercase zh-hans, while the file name stays
zh-Hans.json (required by the framework's materialize step) and the
select value stays zh-Hans (used to build the file path).
