Acceptance Criteria fulfillment

• [x] Update BookmarkService.reset_bookmarks in DEFAULT_SYNC_DAYS setter to reset all bookmarks if default sync days is update or increase

Proposed changes (including videos or screenshots)

• Add _handle_settings_update_side_effect method in settings func to handle any sideeffect for setting updations. -> not recommended unless necessary. This was done to avoid sharing of this context to bff.
• Handle bookmark resetting for default sync days updation. If bookmark resetting fails, the setting change is reverted.
