Team Channels search returns no results when query includes leading or trailing whitespace

Description:

Searching for channels in the Team Channels panel returns no results when the search query contains leading or trailing whitespace.

For example, searching for general correctly returns the matching team channel, while searching for general , general, or general returns no results even though the search term is otherwise identical.

Steps to reproduce:

1. Open any team.
2. Open the Team Channels panel.
3. Search for an existing channel using its name (for example, general) and verify that it is returned.
4. Search again using the same channel name with leading or trailing whitespace (for example, general , general, or general ).

Expected behavior:

Leading and trailing whitespace should be ignored, and the search should return the same channels as the trimmed search term.

Actual behavior:

No matching channels are returned when the search query contains leading or trailing whitespace.

Additional context

The issue is reproducible with both leading and trailing whitespace in the search query. Empty searches continue to behave as expected and display the available team channels.

Relevant logs:

No relevant server or browser errors were observed.

Start at the Team Channels panel and trace how its search query is handled, then reproduce the issue with leading and trailing whitespace around an existing channel name such as general. Done means whitespace-padded queries return the same channels as the trimmed query, while empty searches continue to show available channels; verify the behavior in the Team Channels search flow.
