Move offline sync settings to Web Client Settings section

Relocate com.mendix.offline.DeleteAutoCommittedObjectsAfterSync and com.mendix.offline.SynchronizationCleanupInterval from the Advanced Custom Settings page to the main Runtime Customization reference, placing them in the Web Client Settings section where they are more discoverable.

Changes:
- Move DeleteAutoCommittedObjectsAfterSync from tricky-custom-runtime-settings.md to _index.md
- Move SynchronizationCleanupInterval from Database Settings to Web Client Settings in _index.md
- Add deprecation note to DeleteAutoCommittedObjectsAfterSync indicating it should only be changed for Mendix 9 compatibility issues
- Group both offline-related settings together in Web Client Settings for better organization
