UI improvements: pagination, search, and bulk actions for templates

[alexnet123]

Hi, thanks for the great project 👍
Working with many task templates is difficult due to some UI limitations:
No bulk selection (no checkboxes → no mass delete/run)
No pagination (all templates on one page)
No search/filtering (hard to find templates)
With 100+ templates, the UI becomes hard to use.
Suggestion
Please consider adding:
Checkboxes + bulk actions
Pagination
Search by name
These would greatly improve usability at scale.
Thanks!
