* fix(security): sanitize exception messages in API responses (FIX-11)
Replace raw e.message/error.message interpolations in response bodies
with generic error strings, and log class+message server-side. Prevents
leaking internal exception details (stack traces, SQL fragments, record
data) to API clients.
Covers:
- API v1 accounts, categories (index/show), holdings, sync, trades,
transactions (index/show/create/update/destroy), valuations
(show/create/update): replace "Error: #{e.message}" with
"An unexpected error occurred".
- API v1 auth: device-registration rescue paths now log
"[Auth] Device registration failed: ..." and respond with
"Failed to register device".
- WebhooksController#plaid and #plaid_eu: log full error and respond
with "Invalid webhook".
- Settings::ProvidersController: generic user-facing flash alert,
detailed log line with error class + message.
Updates providers_controller_test assertion to match sanitized flash.
* fix(security): address CodeRabbit review
Major — partial-commit on device registration failure:
- Strengthened valid_device_info? to also run MobileDevice's model
validations up-front (device_type inclusion, attribute presence), not
just a flat "are the keys present?" check. A client that sends a bad
device_type ("windows", etc.) is now rejected at the API boundary
BEFORE signup commits any user/family/invite state.
- Wrapped the signup path (user.save + InviteCode.claim + MobileDevice
upsert + token issuance) in ActiveRecord::Base.transaction. A
post-save RecordInvalid from device registration (e.g., racing
uniqueness on device_id) now rolls back the user/invite/family so
clients don't see a partial-account state.
- Rescue branch logs the exception class + message ("#{e.class} - #{e.message}")
for better postmortem debugging, matching the providers controller
pattern.
Nit:
- Tightened providers_controller_test log expectation regex to assert on
both the exception class name AND the message ("StandardError - Database
error"), so a regression that drops either still fails the test.
Tests:
- New: "should reject signup with invalid device_type before committing
any state" — POST /api/v1/auth/signup with device_type="windows"
returns 400 AND asserts no User, MobileDevice, or Doorkeeper::AccessToken
row was created.
Note on SSO path (sso_exchange → issue_mobile_tokens, lines 173/225): the
device_info in those flows comes from Rails.cache (populated by an earlier
request that already passed valid_device_info?), so the pre-validation
covers it indirectly. Wrapping the full SSO account creation (user +
invitation + OidcIdentity + issue_mobile_tokens) in one transaction would
be a meaningful architectural cleanup but is out of scope for this
error-hygiene PR — filed it as a mental note for a follow-up.

* Add API test routes and update Doorkeeper token handling for test environment
- Introduced API namespace with test routes for controller testing in the test environment.
- Updated Doorkeeper configuration to allow fallback to plain tokens in the test environment for easier testing.
- Modified schema to change resource_owner_id type from bigint to string.
* Implement API key authentication and enhance access control
- Replaced Doorkeeper OAuth authentication with a custom method supporting both OAuth and API keys in the BaseController.
- Added methods for API key authentication, including validation and logging.
- Introduced scope-based authorization for API keys in the TestController.
- Updated routes to include API key management endpoints.
- Enhanced logging for API access to include authentication method details.
- Added tests for API key functionality, including validation, scope checks, and access control enforcement.
* Add API key rate limiting and usage tracking
- Implemented rate limiting for API key authentication in BaseController.
- Added methods to check rate limits, render appropriate responses, and include rate limit headers in responses.
- Updated routes to include a new usage resource for tracking API usage.
- Enhanced tests to verify rate limit functionality, including exceeding limits and per-key tracking.
- Cleaned up Redis data in tests to ensure isolation between test cases.
* Add Jbuilder for JSON rendering and refactor AccountsController
- Added Jbuilder gem for improved JSON response handling.
- Refactored index action in AccountsController to utilize Jbuilder for rendering JSON.
- Removed manual serialization of accounts and streamlined response structure.
- Implemented a before_action in BaseController to enforce JSON format for all API requests.
* Add transactions resource to API routes

- This enhancement supports comprehensive transaction management within the API.
* Enhance API authentication and onboarding handling
- Updated BaseController to skip onboarding requirements for API endpoints and added manual token verification for OAuth authentication.
- Improved error handling and logging for invalid access tokens.
- Introduced a method to set up the current context for API requests, ensuring compatibility with session-like behavior.
- Excluded API paths from onboarding redirects in the Onboardable concern.
- Updated database schema to change resource_owner_id type from bigint to string for OAuth access grants.

* Add API transactions controller warning to brakeman ignore
The account_id parameter in the API transactions controller is properly
validated on line 79: family.accounts.find(transaction_params[:account_id])
This ensures users can only create transactions in accounts belonging to
their family, making this a false positive.
