Two small follow-ups to the out-of-band git-history rewrite that
purged L@ker$2010 / L@kers2010 / L@ker\$2010 from every branch and
tag:

.gitleaks.toml:
  - Regex was L@kers?\$?2010 which catches the expanded form but
    NOT the shell-escaped form (L@ker\$2010) that slipped past PR #3
    in scripts/setup-database.sh. PR #13 fixed the live leak but did
    not tighten the detector. New regex L@kers?\\?\$?2010 catches
    both forms so future pastes of either form fail CI.
  - Description rewritten without the literal password (the previous
    description was redacted by the history rewrite itself and read
    'Legacy hardcoded ... (***REDACTED-LEGACY-PW*** / ***REDACTED-LEGACY-PW***)'
    which was cryptic).

docs/SECURITY.md:
  - New 'History-purge audit trail' section recording what was done,
    how it was verified (0 literal password matches in any blob or
    commit message; 0 legacy-password findings from a post-rewrite
    gitleaks scan), and what operator cleanup is still required on
    the Gitea host to drop the 13 refs/pull/*/head refs that still
    pin the pre-rewrite commits (the update hook declined those refs
    over HTTPS, so only an admin on the Gitea VM can purge them via
    'git update-ref -d' + 'git gc --prune=now' in the bare repo).
  - New 'Re-introduction guard' subsection pointing at the tightened
    regex and commit 78e1ff5.

Verification:
  gitleaks detect --no-git --source . --config .gitleaks.toml   # 0 legacy hits
  git log --all -p | grep -cE 'L@ker\$2010|L@kers2010'         # 0
