auth-bundle-1 Phase 13 follow-up: em-dash sweep + broken-link fix

Self-audit on e7a94b6 flagged the prompt's 'zero em dashes'
discipline rule. The four new Phase 13 docs and the v2.1.0
CHANGELOG section had 97 em-dash hits between them; this commit
sweeps them all to ASCII hyphens.

Counts before -> after:
  docs/operator/rbac.md                  28 -> 0
  docs/operator/auth-threat-model.md     36 -> 0
  docs/migration/api-keys-to-rbac.md     16 -> 0
  docs/operator/security.md               8 -> 0
  docs/reference/profiles.md              3 -> 0
  CHANGELOG.md                            6 -> 0

Mechanical: ' - ' (spaced em dash) and bare em-dash both replaced
with spaced ASCII hyphen, then double-spaces collapsed. Markdown
list bullets ('^- ', '^  - ', '^    - ') verified intact across
all six files. Internal-link sweep also re-run.

Also fixes a pre-existing broken link the audit caught:
  docs/operator/security.md:70 referenced
  '../internal/crypto/encryption.go' which is a 1-level-up jump
  from docs/operator/, not the 2-level-up jump it actually needs
  ('../../internal/crypto/encryption.go'). Pre-Bundle-1 link rot;
  fixed in lockstep so the merge gate's docs validation passes
  cleanly.

Final state across the Phase-13 docs + CHANGELOG:
  - 0 em dashes
  - 0 broken internal links
  - Last-reviewed: 2026-05-09 header on every new doc

Bundle 1 documentation is now ready for the operator-side merge
gate review.
