## What
Unifies keys that were repeated across the codebase into two PHP enums
as the single source of truth. Two independent commits:
### `refactor(banking)` — `BankingProvider` enum
- New `App\Enums\BankingProvider` (`indexacapital`, `binance`,
`bitpanda`, `coinbase`, `wise`, `enablebanking`).
- `BankingConnection`'s `provider` column is cast to the enum → magic
strings gone from the model, controllers (`match`), requests, jobs,
commands, factory and `where('provider', ...)`.
- Logic that was duplicated, now on the enum:
- `usesApiKey()` — API-key auth (everything except EnableBanking).
- `defaultAccountType()` — provider → account type (removes the
duplicated ternary in `CreatesAccountsFromPending` and
`AccountMappingController`).
### `refactor(i18n)` — `Locale` enum
- New `App\Enums\Locale` (`en`/`es`/`fr`).
- Unifies the `['en','es','fr']` list (validation in `SetLocale` and
`ProfileUpdateRequest` via `Rule::enum`) and the `Accept-Language`
detection (`Locale::detectFromHeader`), previously duplicated in
`SetLocale` and `CreateNewUser`.
## Interaction with Wise (PR #525)
Rebasing onto Wise surfaced two issues this PR fixes:
1. **`isWise()` was broken** once `provider` is cast (it compared `===
'wise'` against an enum → always `false`).
2. **Account type**: Wise uses an API key (✓ it gets the auth-failed
email) but is a **checking** account, not an investment one. Account
type now flows through `defaultAccountType()` (Wise/EnableBanking →
Checking; indexa/binance/bitpanda/coinbase → Investment).
## Behavior change (minor)
`CreateNewUser` now detects `fr` at registration (previously only
`es`/`en`), consistent with the existing French support.
## Out of scope
- Frontend (`['indexacapital','binance',...]`, `provider: string`):
syncing TS with the PHP enums would need typegen. It still receives the
string via `->value`.
- `TransactionSource::Wise/EnableBanking`: a separate enum (transaction
origin), not a duplicated check.
## Tests
- New: `tests/Unit/Enums/BankingProviderTest.php`,
`tests/Unit/Enums/LocaleTest.php`.
- `vendor/bin/pint --test` ✓ · Larastan ✓ · full suite (excluding
Browser) **1615/1616** ✓.
## Summary
- sync user currency from the first account, manual or connected
- reuse one service across manual creation and open banking
mapping/auto-create flows
- keep later accounts from overwriting user currency
- add browser signup + onboarding account creation coverage
## Prod check
- users with any account: 210
- first account currency mismatches user currency: 64
- USD user + EUR first account: 36
- first account manual users: 189
- manual-first mismatches: 61
