loki: Simplify loki.yaml

Loki v2.4.0 introduced a common config section[1][2] making the config much smaller and better defaults.

So stripped loki.yaml down, removed options where the default is "good enough" and tweaked retention settings per the upgrade notes[3].

So the config should basically be the example loki.yaml[4] + compactor, retention enabled and a few tweaks (ex: compress chunks with zstd).
