utils/disk_space_monitor: add error injection to suppress threshold checks

Browse Source 
Add the `suppress_disk_space_threshold_checks` error injection point
to the disk space monitor. When enabled, the threshold listener
short-circuits without evaluating disk utilization.

This is useful for tests that override disk capacity via `data_file_capacity`,
where the real disk usage causes the monitor to incorrectly report
critical utilization and activate out-of-space prevention mechanisms.
