feat(auth): support combined and salted digest schemes from any CMS

Browse Source

Expand checkLogin to auto-detect and migrate every common retro CMS password
format to bcrypt on login:
- combined digests: md5(md5(pass)), md5(sha1(pass)), sha1(md5(pass)),
  double sha1/sha256/sha512 and md5<->sha256/sha512 combinations
- salted digests of all families (md5/sha1/sha256/sha512) with embedded
  salt using : $ @ _ separators, verifying both salt+pass and pass+salt
- plaintext fallback stays as the final catch-all

All formats verified on login and rewritten to bcrypt, so accounts work
whenever they come from any legacy CMS.
