fix: Fix OsRng import and refactor Redis connection setup

- Fix password-hash version mismatch (0.6→0.5) causing OsRng to be
  gated behind missing getrandom feature; enable argon2 rand feature
- Extract get_redis_connection() helper to deduplicate Redis client
  setup across authentication, repo control, and tests
- Tighten username validation regex to require ≥2 chars and disallow
  leading/trailing dots or hyphens
- Handle malformed cookies without split_once gracefully (continue
  instead of panic)
- Fix typos: "rated commands" → "related commands" in CLI help text
