android: ktlint forces a multiline signature at two parameters

`resolvedNoteColor` and `noteTintFor` are the first non-composable functions
here to take more than one parameter, and ktlint_official's function-signature
rule requires each parameter on its own line once there are two or more. Four
findings on one and four on the other, all the same rule.

Nothing had type-checked: ktlint is step 6 and the unit tests are step 8, so the
fixture pinning the derived-tint mirror never ran.

I checked line width, trailing whitespace and KDoc adjacency before pushing —
the three that have bitten before — and not this one. The list of rules learned
by failing CI is not the list of rules.
