 ### Added
 
+- **Accounts view** (PRD §6.4, PRD-v2 §P1.4, task 23): full Accounts management UI replacing the previous `PlaceholderView`. Header tabs (`All` / `Debrid` / `Premium` / `Free`) drive a category filter on top of the SQLite-backed `account_list` query, with the `(filter, all)` count rendered next to each label. Each row exposes the service, username, account type, derived status badge (`Active` / `Expired` / `Disabled` / `Unverified`), an aria-labelled traffic progress bar (used / total formatted via `formatBytes`), `valid_until` and `last_validated` columns, an enable/disable `Switch`, an inline `Validate` button, and a kebab menu with `Edit` / `Delete`. The new `AddAccountDialog` validates non-empty service / username / password before submission. `EditAccountDialog` posts a partial `AccountPatch` (skips fields that did not change so the keyring rotation only fires when the password field is filled). The `Delete` action honours the existing `settings.confirm_delete` toggle: when enabled it pops the new `DeleteAccountDialog` (translated description naming the row), otherwise it deletes immediately. `ImportAccountsDialog` calls `tauri-plugin-dialog`'s file-pick to anchor the encrypted bundle path, prompts for the passphrase, then calls `account_import` and invalidates the list cache so freshly-imported rows appear without a manual refresh; `ExportAccountsDialog` requires the user to confirm the passphrase, opens the native `save` dialog for the destination, and reports the row count via toast. Eight new Tauri IPC commands wire the existing `CommandBus` / `QueryBus` handlers (tasks 21, 22) to the frontend: `account_add`, `account_update`, `account_delete`, `account_validate`, `account_export`, `account_import`, `account_list`, `account_get`, `account_traffic_get`, all registered in `invoke_handler!` and re-exported from `lib.rs`. The runtime now wires `SqliteAccountRepo` to both buses and provides the `KeyringAccountStore` + `AesGcmPbkdf2Codec` adapters to the `CommandBus`. Adds `useAccountsQuery` (TanStack Query, 30 s `staleTime`) and `accountQueries` cache key factory. New i18n namespace `accounts.*` covers titles, status badges, dialog copy and toast messages in `en.json` + `fr.json`. 13 Vitest tests cover render, empty state, category filter, add → IPC → toast flow, delete → confirm → IPC, export trigger disabled when no accounts, export with passphrase, import with file picker. `AccountValidator` is intentionally not wired in this commit — `account_validate` returns the configured `Validation` error until the first hoster plugin lands (task 38), letting the UI render the failure toast without crashing. The "volume per account" stat from the requirements list is deferred until `history` gains an `account_id` column.
 - **Accounts queries** (PRD §6.4, PRD-v2 §P1.3, task 22): three CQRS query handlers (`list_accounts`, `get_account`, `get_account_traffic`) wired through the `QueryBus` builder via a new `with_account_repo` setter. New read models `AccountViewDto` and `AccountTrafficDto` (`#[serde(rename_all = "camelCase")]`) expose every persisted field — `id`, `service_name`, `username`, `account_type`, `enabled`, `traffic_left`, `traffic_total`, `valid_until`, `last_validated`, `created_at`, `credential_ref` — and never carry a password or raw credential field, by construction. `AccountFilter { service_name?, account_type?, enabled? }` AND-combines filters: `service_name` is delegated to the repo's `list_by_service` for SQL-level pruning, while `account_type` and `enabled` filter in memory. `get_account_traffic` returns the persisted counters; the upstream-refresh path is the existing `account_validate` command (task 21), keeping queries side-effect free per the project CQRS rule. 21 new unit tests against an `InMemoryAccountRepoForQueries` fixture cover filter combinations, missing-id 404s, missing-repo validation errors, camelCase serialization shape, and explicit "no password field" assertions on `serde_json::to_value` output. Unblocks task 23 (Vue Accounts).
 - **Accounts commands** (PRD §6.4, PRD-v2 §P1.2, task 21): six application-layer command handlers (`add_account`, `update_account`, `delete_account`, `validate_account`, `export_accounts`, `import_accounts`) wired through the `CommandBus` builder. New driven ports `AccountCredentialStore`, `AccountValidator` (with `ValidationOutcome`) and `PassphraseCodec` keep handlers free of plugin / crypto dependencies. `KeyringAccountStore` adapter persists per-account passwords under `vortex-account-{id}` keyring entries; `AesGcmPbkdf2Codec` adapter implements the import / export bundle format using AES-256-GCM with a PBKDF2-HMAC-SHA256 200 000-iteration KDF, fresh per-call salt + nonce, header bound as AAD, and a `VORTACC` magic + version byte so tampered or downgraded bundles fail authentication. Domain events `AccountAdded`, `AccountUpdated`, `AccountDeleted`, `AccountValidated`, `AccountValidationFailed`, `AccountsImported`, `AccountsExported` published via `EventBus` and forwarded by the Tauri bridge as `account-*` browser events. Add rolls back the SQLite row when the keyring write fails so credentials never end up orphaned; import validates every entry up-front and skips `(service_name, username)` pairs already present without inserting partial state. Unblocks task 23 (Vue Accounts).
 - **Accounts persistence** (PRD §6.4, PRD-v2 §P1.1, task 20): SQLite `accounts` table (migration `m20260428_000006`) with `id` / `service_name` / `username` / `account_type` / `enabled` / `traffic_left` / `traffic_total` / `valid_until` / `last_validated` / `created_at` columns and a UNIQUE `(service_name, username)` index. New `AccountRepository` driven port (`save` / `find_by_id` / `list` / `list_by_service` / `delete`) and `SqliteAccountRepo` adapter with sea-orm entity + `from_domain` / `into_domain` converters. UNIQUE violations surface as `DomainError::AlreadyExists` instead of leaking storage errors. Domain `Account` aggregate gained `traffic_total`, `last_validated`, `created_at` fields and switched its identifier to `AccountId(String)` so generated account ids match the spec's `TEXT PRIMARY KEY`. `Account::credential_ref()` returns a `keyring://{service}/{username}` URI exposing a logical reference suitable for diagnostics; passwords themselves are never persisted to SQLite — they live in the OS keychain via the `AccountCredentialStore` adapter (added in task 21, keyed by `AccountId`). Unblocks tasks 21-25, 38, 51-56, 75-76.
