truongitandClaude Opus 5.5 9e0f14cab9 Open Excel's password-protected workbooks again: accept a hash-size integrity key (#2712 )

Since #2425 checks Agile encryption's dataIntegrity, every workbook Excel
encrypts fails with "the decrypted data failed its integrity check". The
reader keyed the HMAC with the decrypted encryptedHmacKey cut to the salt
size (16 bytes), as [MS-OFFCRYPTO] 2.3.4.14 describes it, but Excel's key
is as long as the hash: 64 bytes for SHA-512. The check now accepts a key
of either length, so spec-literal writers still open and a modified
package still fails.

The test encryptor writes the integrity key as Excel does, so every
encrypted fixture now has Excel's layout; a new test covers both key
lengths, a key of neither length, and tampering with each.
