M6b: core:design fixes after the M7 wave

Bugs: viewerPercentOf reads basis points (Samples in bp); FullSplitPicker and the
split labels use editor_split_full_on_you ("Allt på dig"); AmountInput.of restores
money with both decimals (AmountInput.percent for ratio fields), replacing M7c's
moneyInput; quickRowCategories does the D-060 fill itself; KvittScaffold resolves
resource-backed snackbars (showKvittSnackbar) while shown.

Gaps: ConfirmDialog optional and styled body; KvittButton loading form (M7a uses it,
ProgressBottomButton removed); InviteCodeField wraps after a group, placeholder,
imeAction; EmptyState icon tile and actionEnabled; DateFormatter.monthName and
dayRangeLong; AnalyticsFilterBar periodOwnRow; segmentedItem builder; screen tokens
in KvittDimens (OnboardingDimens removed); common_ok, common_undo; module-proposed
keys recorded in strings.csv; quick-row labels end in an ellipsis on line two.
