[performance] bump codeberg.org/gruf/go-kv to v2 (#4341)

updates our codeberg.org/gruf/go-kv log key-value formatting library to latest version, which comes with some maaaaaaajor speed boosts in the form of:
- very minimal reflect.Value{} usage
- caching prepared formatting functions per type

~~still a work-in-progress until i make a release tag on the go-kv repository, which itself is waiting on published benchmark results in the README and finishing writing some code comments~~

benchmarks so far show this to be ~3x faster than the "fmt" stdlib package on average, when run across a wide variety (106 different types) of test cases, while still creating more visually friendly log output and actually recursing down nested struct ptrs
