Depth Pooling Fixes

• Fixed np.errstate usage: all_nan is not a valid parameter for errstate. Changed to invalid="ignore".
• Fixed conf_stack possibly unbound error by initializing it to None and checking it before use.
• Removed duplicated unreachable code block after the first return.
• Fixed implicit string concatenation warning in ValueError message.
• Updated type hints to modern Python style (list[], |) and removed unused typing imports.
• Verified with basedpyright (0 errors).
