feat(balance): tile-based landing hub + reachable account management
Decouple the /balance empty-state guard into three explicit states via a
new pure helper `deriveLandingState` (empty / accounts-no-snapshot /
populated). Having accounts but no snapshot no longer strands the user on a
snapshot-only onboarding card: each state now renders navigation tiles
(HubReportNavCard, modeled on the Reports hub), and "Manage accounts"
(/balance/accounts) is reachable in every state, including the populated
dashboard.

- Remove BalanceOnboardingCard (component + test) and the dead
  balance.onboarding.* i18n keys; add balanceLanding.ts + test.
- Add balance.hub.* and balance.landing.* keys in FR and EN.
- CHANGELOG (EN + FR) under [Unreleased].

Resolves #244

// BalancePage — overview of net worth at `/balance`.
//
// Issue #141 (Bilan #3). Composes:
// - BalanceOverviewCard (latest total + Δ% + staleness warning + new-snapshot CTA)
// - Period selector (3M / 6M / 1A / 3A / Tout)
// - Chart-mode toggle (Line / Stacked-by-category)
// - BalanceEvolutionChart
// - BalanceAccountsTable (one row per active account with latest value + Δ%)
//
// All data flows through `useBalanceOverview` (scoped useReducer). Returns
// (Modified Dietz) are deferred to Issue #142 — the accounts table reserves
// columns with a TODO comment.
