Increased bulk action limit for conversations

Business problem

There is currently a technical limitation when attempting to delete or close more than 50 tickets simultaneously. This makes it difficult and time-consuming to clear out old backlogs of outdated or unnecessary conversations.

Wished result

The ability to perform bulk actions (closing or deleting) on more than 50 conversations at once. To prevent accidental data loss, a double confirmation step could be implemented instead of a hard limit on the number of tickets.
