Critical fixes:
- Add [:safe] option to binary_to_term to prevent RCE attacks
- Implement whitelist validation for String.to_atom conversions
- Add input validation before String.to_existing_atom usage
Changes:
- MIB compiler and cache: Use safe binary deserialization
- SNMP contexts: Whitelist protocol, device type, and source atoms
- API controllers: Validate error message keys before atom conversion
- Reduce function nesting to comply with Credo standards
All 6,145 tests passing with zero Credo issues.

Created API token system for programmatic access:
- API tokens table with organization scoping
- ApiTokens context for token management
- ApiAuth plug for Bearer token authentication
- Tokens shown once on creation, then hashed for security
Implemented RESTful API v1 endpoints:
- SitesController: CRUD operations for sites
- DevicesController: CRUD operations for devices
- All operations scoped to authenticated organization
- Proper authorization checks via site ownership
Technical details:
- Tokens prefixed with "towerops_" for easy identification
- SHA-256 hashing for token storage
- Last used timestamp tracking (async update)
- Optional token expiration support
- Standard JSON error responses (40x status codes)
Routes:
- /api/v1/sites (GET, POST, PATCH, DELETE)
- /api/v1/devices (GET, POST, PATCH, DELETE)
Authentication:
- Authorization: Bearer towerops_xxxxx header required
- Returns 401 for invalid/expired tokens
- Returns 403 for unauthorized resource access
