Replace mypy>=1.8.0 with pyright>=1.1.390. Remove all [tool.mypy] and
[tool.pydantic-mypy] sections from pyproject.toml and add
pyrightconfig.json (standard mode, SQLAlchemy false-positive rules
suppressed globally).
Fixes surfaced by pyright:
- Remove unreachable except AuthError clauses in login/login_oauth (same class as AuthenticationError)
- Fix Pydantic v2 list Field: min_items/max_items → min_length/max_length
- Split OAuthProviderConfig TypedDict into required + optional(email_url) inheritance
- Move JWTError/ExpiredSignatureError from lazy try-block imports to module level
- Add timezone-aware guard to UserSession.is_expired to match sibling models
- Fix is_active: bool → bool | None in three organization repo signatures
- Initialize search_filter = None before conditional block (possibly unbound fix)
- Add bool() casts to model is_expired and repo is_active/is_superuser returns
- Restructure except (JWTError, Exception) into separate except clauses
- Consistently format multi-line function headers, exception handling, and repository method calls for readability.
- Reorganize misplaced imports across modules (e.g., services & tests) into proper sorted order.
- Adjust indentation, line breaks, and spacing inconsistencies in tests and migration files.
- Cleanup unnecessary trailing newlines and reorganize `__all__` declarations for consistency.
- Deleted `I18N_IMPLEMENTATION_PLAN.md` and `PROJECT_PROGRESS.md` to declutter the repository.
- These documents were finalized, no longer relevant, and superseded by implemented features and external references.
- Enforced stricter PKCE requirements by rejecting insecure 'plain' method for public clients.
- Transitioned client secret hashing to bcrypt for improved security and migration compatibility.
- Added constant-time comparison for state parameter validation to prevent timing attacks.
- Improved error handling and logging for OAuth workflows, including malformed headers and invalid scopes.
- Upgraded Google OIDC token validation to verify both signature and nonce.
- Refactored OAuth service methods and schemas for better readability, consistency, and compliance with RFC specifications.
- Implemented stricter OAuth security measures, including CSRF protection via state parameter validation and redirect_uri checks.
- Updated OAuth models to support timezone-aware datetime comparisons, replacing deprecated `utcnow`.
- Enhanced logging for malformed Basic auth headers during token, introspect, and revoke requests.
- Added allowlist validation for OAuth provider domains to prevent open redirect attacks.
- Improved nonce validation for OpenID Connect tokens, ensuring token integrity during Google provider flows.
- Updated E2E and unit tests to cover new security features and expanded OAuth state handling scenarios.
- Added models for `OAuthClient`, `OAuthState`, and `OAuthAccount`.
- Created Pydantic schemas to support OAuth flows, client management, and linked accounts.
- Implemented skeleton endpoints for OAuth Provider mode: authorization, token, and revocation.
- Updated router imports to include new `/oauth` and `/oauth/provider` routes.
- Added Alembic migration script to create OAuth-related database tables.
- Enhanced `users` table to allow OAuth-only accounts by making `password_hash` nullable.
