Migrate server.accept() to use argumentsAsArray

Replaced .arguments_old() with .argumentsAsArray() to comply with
codebase ban on .arguments_old().

- Simplified argument handling by using argumentsAsArray(1)[0]
- Removed manual length check (argumentsAsArray handles this)
- Clarified SSL documentation wording slightly
