Savya Sanchi Sharma 68fd896a44 Merge pull request #30173 from SavyaSanchi-Sharma:calib/fisheye
Calib: assersion fix of fisheye calib - #30173

Replaces a CV_Assert in fisheye::InitExtrinsics with a graceful failure path (returns bool, caller now throws a descriptive StsBadArg naming the degenerate view) instead of crashing on a hard assert. Also adds validation that rejects legacy numeric  flag values passed to fisheye::calibrate/stereoCalibrate, and fixes CALIB_CHECK_COND to actually gate the condition check in stereo calibration. Includes an hdr_parser.py change to resolve using Base::CONST enum aliases for Python bindings.
