Android overhaul: shared failure texts, saved-split label and limits in :core:design

* format/Failures.kt: FAILURE_NETWORK and commonFailureText, the §14.3.2 code-to-text map that :feature:account
  (Errors.kt) and :feature:settings (Messages.kt) each spelled out; both keep only their own codes. The "network"
  literals in :feature:onboarding and the two NETWORK constants use FAILURE_NETWORK.
* component/Split.kt: savedSplitLabel, the S-8 and S-16 line ("Kontots standard 50/50", "Egen fördelning 70/30",
  "Exakta belopp", "Allt på dig/Anna") that ExpenseDetailScreen.modeLabel and SyncStatusScreen.lostModeLabel
  duplicated line for line.
* format/Limits.kt: BP_TOTAL (five copies in four features and a literal in :core:design and S-19) and
  DISPLAY_NAME_MAX (three copies in :feature:onboarding and :feature:settings).

Behaviour and goldens unchanged.
