style: apply ruff format across the tree; refresh moved-module doc refs

Bring 14 files that predated the ruff-format run into line with the configured
formatter (line-length 100); provably formatting-only (ruff format of HEAD ==
working tree, and ruff format is semantics-preserving). Also refresh two
lim.image.tor._KEYGEN_SCRIPT doc references in tor_harness.py to
lim.image.initramfs.keygen after the module moved.
