feat: surface Simplified Chinese; complete 2.14.0 changelog

Add zh-CN to locales_config.xml so the community Simplified Chinese
translation (values-zh-rCN, already committed via Weblate, ~27%) is
selectable in the in-app language picker and Android's per-app-language
settings. Untranslated strings fall back to English.

Fill in the 2.14.0 changelog, which only documented #37: add the three
feature PRs that also landed on this branch — .ics restore + per-calendar
export (#32), Month week numbers (#25), edit-screen title wrapping (#33) —
plus a note for the new Chinese translation, the missing [#N] link refs,
and the re-synced fastlane en-US changelog.

 ### Added
+- Restore events from a backup file. The backup section of Settings can now read
+  events back **in** from an `.ics` file, not just write one out: pick a file,
+  choose which calendar to import into, and Calendula adds the events — skipping
+  any that are already there and telling you how many it skipped. Export gained a
+  per-calendar selector at the same time, so you can back up just the calendars
+  you pick instead of everything at once ([#32]).
+- Week numbers in Month view. A new **Week numbers** setting (off by default)
+  adds a slim gutter down the left of the Month grid showing the calendar-week
+  number for each row, sized to match the day cells. Handy if you plan or refer
+  to dates by week number ([#25]).
 - Tap a date header to open that day. In Week and Agenda view, tapping a date
   header now opens that date in Day view — the same drill-in that Month view and
   the agenda widget already offered, so every view behaves the same way. It makes
   jumping to a specific day quicker: switch to Week, swipe to the week you want,
   then tap the date to open it. Thanks to @ptab for the suggestion ([#37]).
+- An early Simplified Chinese translation. Calendula has started speaking
+  Simplified Chinese, contributed as a community translation through
+  [Calendula's Weblate](https://weblate.dev.jeanlucmakiola.de/projects/calendula/).
+  It is still an early effort, so many parts of the app show in English until it
+  fills out — you can already pick it under Settings → Language or in Android's
+  per-app language settings. Thanks to
+  [zh-cn](https://weblate.dev.jeanlucmakiola.de/user/zh-cn/) for getting it
+  started; help finishing it is very welcome.
+
+### Changed
+- Long event titles wrap in the edit screen. When editing an event, a long title
+  now wraps onto multiple lines instead of being clipped to a single line, so you
+  can see and edit the whole thing ([#33]).
