Remove static Users auth, use shared QualityMapper for historian, simplify LDAP permission checks

Browse Source 
- Remove ConfigUserAuthenticationProvider and Users property — LDAP is the only auth mechanism
- Fix historian quality mapping to use existing QualityMapper (OPC DA quality bytes, not custom mapping)
- Add AppRoles constants, unify HasWritePermission/HasAlarmAckPermission into shared HasRole helper
- Hoist write permission check out of per-item loop, eliminate redundant _ldapRolesEnabled field
- Update docs (Configuration.md, Security.md, OpcUaServer.md, HistoricalDataAccess.md)
