fix: use Qt flag_val() for PySide6 compat in IDA plugin

Replace direct bitwise operations on module-level Qt flag constants
with flag_val() helper that extracts int values from enum members.
This resolves RuntimeWarning in IDA 9.3+ where PyQt5 shim is deprecated.

Changes:
- qt_compat.py: add flag_val(), fix qt_get_item_flag_tristate() to
  return int value using proper enum path
- item.py: use flag_val() for all flag bitwise operations
- view.py: use flag_val() for all flag bitwise operations
