[full-ci] enhancement: use kql as default search query language

[fschade]

Description

follow up pr for #7043, this enables and uses the kql query language as the default dialect for search queries.

enabled for the following endpoints (used by web as default):~~

• /remote.php/dav/spaces*
• /dav/spaces*
• /remote.php/dav/files*
• /dav/files*

the endpoints /remote.php/dav/files* and /dav/files* are not affected by this and continue to use the legacy query format.
