[Copilot]

Pull Request Overview

Refactors Android calendar interactions by replacing ical4android with the new synctools provider API and consolidates logging to use the shared synctools formatter.

• Bumps the bitfire-synctools dependency to the new commit ID.
• Swaps all imports and calls from at.bitfire.ical4android.* to at.bitfire.synctools.*, introducing AndroidCalendarProvider methods.
• Removes the local PlainTextFormatter and its tests in favor of the one provided by synctools, and updates logging handlers accordingly.

• [nitpick] Since you’re adding a new handler on every initialization, you may end up with duplicate log outputs if this runs multiple times. Consider clearing existing handlers first or ensuring this is only called once.

        rootLogger.addHandler(LogcatHandler(BuildConfig.APPLICATION_ID))
