## What & why
Import configuration (the CSV/Excel column mapping and date format a
user
sets up per account) was stored in the browser's `localStorage`, so it
never
followed the user to another device. Importing the same account's
statement on
mobile — or on a new machine — meant reconfiguring the mapping from
scratch.
This moves that configuration to the backend, keyed per account and per
import
type, so it's preconfigured and loaded automatically wherever the user
imports.
## Demo
Cross-device QA: import transactions on "device 1" with a custom column
mapping, then clear **all** cookies + local/session storage (simulating
a
fresh device), log back in, and start a new import — the mapping
(Description → *Movement*, Amount → *How Much*, date format
*DD-MM-YYYY*)
is auto-loaded from the backend with no manual setup.

## How
- New `account_import_configs` table: one row per `(account_id, type)`
where
`type` is `transaction` or `balance`. The mapping + date format are
stored as
an opaque `config` JSON blob (exactly what the client sends).
- `GET/PUT /api/accounts/{account}/import-config`
(`AccountImportConfigController`),
authorized via the existing `AccountPolicy` (`view`/`update`) — mirrors
`AccountBalanceController`. `PUT` upserts on `(account_id, type)`.
- Frontend: the two import-config storage helpers now read/write the
endpoint
via `axios` instead of `localStorage` (merged into a single module — the
transaction and balance variants shared the same logic).
- The saved config is fetched **off the file-parse critical path**: the
parsed
file shows immediately with auto-detected columns, and the saved mapping
is
applied when it arrives (guarded so a slow load can't clobber a file
picked
afterwards). A slow or hanging request never blocks the preview or Next
button. When no config exists or the request fails, it falls back to
auto-detection exactly as before.
## Notes / decisions
- **No localStorage migration.** Existing per-device configs aren't
migrated;
on the next import the mapping is auto-detected and re-saved to the
backend,
so it self-heals after one import. The old `import_config_account_*`
keys are
simply no longer read.
- The mapping-validity check against the actual file headers stays
client-side
(it depends on the just-parsed file).
## Testing
- `tests/Feature/AccountImportConfigTest.php` (9 tests): auth required,
cross-user 403 on read and write, save→persist→load round-trip, upsert
de-duplication, transaction/balance independence, and validation
(unknown type, missing column mapping).
- Sibling suites green (`AccountBalanceControllerTest`,
`SavedFilterTest`) —
no regression from the new `Account::importConfigs()` relation or
routes.
