Update QUICHE to use Bazel 7.4.1, but without bzlmod for now

Enabling bzlmod almost works, but there's some weird issue with zlib that seems to stem from a second zlib getting pulled in automatically? Introducing a `MODULE.bazel` and switching most deps to it seems to fix that, but let's update Bazel first, just to isolate any issues caused by the two.
