* Fix hibernation crash on fresh Windows 11 25H2 (BSOD Event 41)
* follow up on the hibernation fix review: fix MDL check order and drop the risky sleep.
- Document HIGH_LEVEL constraints and rationale for pre-building a nonpaged scratch MDL.
- Allocate contiguous scratch buffer with conservative PFN cap (0x7FFFFFFFFFF) and fall back to unlimited cap if needed.
- Replace ASSERT with TC_BUG_CHECK for validation of write MDL mapping at HIGH_LEVEL.
- Safely copy PFNs from prebuilt MDL into caller MDL: compute dst/src page counts, check capacity, copy exact PFNs and retarget MDL header fields (preserve MdlFlags).
- Make DumpData cleanup defensive in unload path.
- comments improvements for clarity and maintainability.
* Prefer allocations to be non-executable
* Remove and reimplement DDIs inappropriately called inside HIGH_LEVEL IRQL routines
* Refactor hibernate context to be passed around in the passed FILTER_EXTENSION pointer rather than global
