refactor: Change Calendar's default event syncing time from 90 days to 1 year
Description
On /e/OS's Calendar app, events older than 3 months don't show up although the web version of the calendar shows them.
To improve the behavior of the Calendar app, the event syncing period has been increased to 365 days from the previously set 90 days in the AccountManager app.
Tests
Tests have been performed to check if events scheduled older than 3 months show up in the Calendar app. Events older than 365 days will not be synced and hence will not show up on Calendar.
