Improve ticket admin page #741
Description
The admin page for tickets just lists barcodes and emails - it would be good to add some filtering / search options to it for the cases where a ticket needs to be manually updated or some error in the sync between Quicket and wafer needs to be investigated.
Things that seem use off the top of my head:
Filtering by ticket type
Searching by email
Searching by barcode
(Both of these are possible using browser search, but that's more painful when multiple pages of tickets need to be searched)
It would also be nice to have some sort of feature for easily finding tickets with duplicate info - probably should be a filter that can be combined with the ticket type filter
