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)

## LDAP Authentication
The server supports LDAP-based user authentication via the `Authentication.Ldap` section in `appsettings.json`. When enabled, credentials are validated by LDAP bind against a GLAuth server (installed at `C:\publish\glauth\`), and LDAP group membership maps to OPC UA permissions: `ReadOnly` (browse/read), `ReadWrite` (read/write tags), `AlarmAck` (alarm acknowledgment). The `IUserAuthenticationProvider` interface is pluggable — `LdapAuthenticationProvider` implements both `IUserAuthenticationProvider` and `IRoleProvider`. See `docs/Security.md` for the full guide and `C:\publish\glauth\auth.md` for LDAP user/group reference.
