Merge pull request 'fix(calendar): convert event times to local timezone on parse' (#15) from dev into main

Offline queue (SharedPreferences) persists captures when the device
is offline and replays them as chat conversations on next launch,
preserving the same fire-and-forget guarantee as the online path.
