fix(code-review): resolve Batch 1 open findings (AdminUI auth, AlarmHistorian dispose guards, docs)

- AdminUI-001: gate Script editor pages at Administrator,Designer + loosen ScriptAnalysis backend to match
- AdminUI-004: explicit [Authorize] on FleetStatus/Alert/ScriptLog hubs
- Core.AlarmHistorian-014: ObjectDisposedException guards on GetStatus/RetryDeadLettered (+ regression test)
- Core.Scripting.Abstractions-004/-007: Deadband tolerance doc + stale ScriptedAlarms.md path
- Host-003: correct config-overlay precedence in ServiceHosting.md
- Configuration-014: LdapGroupRoleMapping collation-dependency doc
- Driver.TwinCAT.Contracts-002: Structure enum doc (discovery-only sentinel)
