fix(vector config): fix match_any crash on null (not exist) namespace_name when pod metadata annotation fails

[vparfonov]

Description

Use fallible string() with null coalescing instead of infallible string!() so events with missing kubernetes metadata default to log_type="application" instead of aborting the remap transform.
