UI: Template/ISO filtering and search not working

[RosiKyu]

problem

Template filtering does not work in the UI. Neither the simple search box nor the advanced filter panel filters the template list.

versions

4.22

The steps to reproduce the bug

1. Navigate to Images → Templates/ISOs
2. Attempt filtering using either method:

Method A - Simple Search:

• Enter a template name (e.g., "Debian 11") in the search box
• Press Enter or click the search icon

Method B - Advanced Filter:

• Click the filter icon next to the search box
• Fill in filter criteria (e.g., Name, Zone, Template type)
• Click "Search"

EXPECTED BEHAVIOR

• Template list should be filtered to show only templates matching the search/filter criteria
• For example, searching "Debian 11" should only show templates with "Debian 11" in the name

ACTUAL BEHAVIOR

• Template list remains unchanged - all templates are displayed regardless of filter criteria
• Search box shows the entered text but filtering is not applied
• Example: Searching "Debian 11" still shows all 5 templates including "Deb 12", "SystemVM Template", "CentOS 5.5", etc.

This issue seems to be present in 4.22.0.0, but not in the current 4.22 branch. This issue was already fixed in #12146
