feat(site): multi-site join server endpoints + persisted site role + emoji fix

Server endpoints for joining a spoke to a master directory (MULTI_SITE_SPEC.md). This pass is server-only; setup.sh wiring and the UI are the next layer. - Site join keys (SiteJoinKey model, stj_ prefix): mint/revoke/delete/list, hashed at rest, shown once — the same model as agent join keys. - POST /api/site/export (master, Bearer stj_ key, no admin session): returns the local LDAP tree (slapcat LDIF) + resource catalog + siteSlug + baseDn. - POST /api/site/join (spoke, admin): { masterUrl, joinKey } pulls the master export, imports resources (upsert by slug) + LDAP (ldapadd -c), and persists the spoke role. Refused if already a spoke. - Persisted site role: utils/site_config.js keeps isMaster/masterUrl/siteSlug in /config/site.json (env seeds defaults); site-status/site-promote now use it. - Unit tests (site_join, site_config) with in-memory stubs, wired into npm test. - docs/site-join.md + docs router entry. - Repairs the corrupted multi-site emojis (crown/bolt) in directory.ejs. - .gitguardian.yml ignores the generic-password false positive on reading the LDAP bind credential from runtime config (never a hardcoded secret).
