refactor: use __fish_palette in system and package functions

44 duplicated declarations replaced by 8 calls. Output strings untouched.

fish-deps, upgrade and wake-lock have no --help path and are deliberately
NOT added to the harness case list -- upgrade and wake-lock have side
effects, and runtime coverage is not worth mutating state during tests.
They are covered by --structural, which proves mechanically that no
rendering line changed.
