* feat(mobile): add privacy mode to mask money values Adds an app-wide "privacy mode" so users can hide monetary amounts from over-the-shoulder view. - PrivacyProvider (ChangeNotifier) backed by PreferencesService, so the choice persists across launches and every money widget rebuilds on toggle. - MoneyMasker.mask() collapses an amount's numeric portion into a short fixed run of bullets while keeping the currency symbol and sign (e.g. CA$1,234.56 -> CA$••••). A fixed run avoids leaking the value's magnitude and reads cleanly without stray separators. Currency- and locale-agnostic — it operates on already-formatted strings. - Masking applied at every money render site: net worth + per-currency totals + breakdown sheet (NetWorthCard), account balances (AccountCard, AccountDetailHeader, transaction form account selector), and transaction amounts (transactions list, recent transactions, calendar). - Two entry points: a "Hide amounts" switch in Settings -> Security, and a quick eye toggle in the top bar (visible on every tab). Tests: MoneyMasker unit tests (fixed-run mask, magnitude hidden, symbol/ sign kept, passthrough, idempotent) + a widget test asserting the net worth masks/unmasks as the provider flips; account_card_test updated to provide the new provider. flutter analyze: no new issues; full suite (123) green. * fix(mobile): address privacy-mode review feedback - Startup masking (Codex P1): read the privacy preference in main() before runApp and seed PrivacyProvider with it, so the first frame already has the correct value — money is never briefly rendered unmasked for a user who enabled "Hide amounts". Provider stays fail-closed otherwise: starts masked, SureApp's no-arg default is masked, and a failed read keeps it masked. A late-completing initial load no longer clobbers an explicit user toggle. - setHidden() reverts the in-memory state (and logs) if persistence fails, keeping the UI consistent with what's actually stored. - Mask the cash-balance detail chip in AccountDetailHeader (was leaking the cash position in privacy mode). - Privacy top-bar toggle gets a "Toggle privacy" tooltip + icon semantic label for accessibility (kept as an InkWell to match the adjacent settings control). - Tests: assert fail-closed initial state; assert the exact masked count; test the persistence round-trip (set -> reload); add PreferencesService.resetForTest() and reset between tests so the cached singleton can't leak state. 125 tests pass; flutter analyze: no new issues. * refactor(mobile): thread hideAmounts through calendar tiles Per review: the calendar tile builders read PrivacyProvider via context.read, relying implicitly on the parent build()'s context.watch to rebuild them — fragile if a tile is later extracted or wrapped in a RepaintBoundary. Pass hideAmounts down explicitly instead, matching the recent_transactions_screen pattern: - build() (context.watch) -> _buildCalendar -> _buildDayCell - _showTransactionsDialog reads once when the modal opens -> _buildTransactionTile No more context.read inside tile methods. 125 tests pass; analyze clean. * fix(mobile): watch PrivacyProvider inside calendar dialog builder Moving the hideAmounts read inside the showDialog builder and switching from context.read to context.watch ensures the dialog re-masks transaction amounts if the user toggles privacy mode while the dialog is open.
