vangel76 3b918ada2c Review: Allow Edit Ranges with Excel-compatible password hashes (#307)
- Model: Sheet.edit_ranges (title, ranges, optional password hash,
  security descriptor) and gridcraft_model::password: the ECMA-376 legacy
  16-bit hash and the salted, iterated SHA-2 hash (SHA-512/384/256; other
  algorithms, damaged hashes and spin counts over 10,000,000 are refused).
  New passwords use SHA-512, spin count 100000. Adds the sha2 crate.
- XLSX: <protectedRanges> read and written; an unreadable password keeps
  the range locked.
- review.allowEditRanges {action: list|add|modify|delete|unlock, ...}: empty
  params list; ranges can't change while the sheet is protected; unlock
  verifies the password for the session. Not journaled (passwords).
- Locked-cell checks (commit guard, cell.set, picture in cell) let edits
  through in open or unlocked ranges; ranges move with structural edits.
- Ribbon button and a form dialog (menu invocation only).
