Final: live fleet monitoring + Azure Monitor (App Insights)

[CarsonL15]

Summary

A significant feature update to the Admin & Maintenance App for the final, adding two more Azure services to the solution and a real-time operations view.

1. Live fleet monitoring (real-time)

• The Bots page now auto-refreshes every 5s and merges the simulator's live runtime telemetry (power level, status) into the registry view, matched by botId.
• A "🟢 Live" indicator with last-updated time + a Pause/Resume control; polling pauses during edits/deletes so it never disrupts the operator.
• Per-bot telemetry shows live power % + status, and flags "no signal"/"offline" when a bot has no live data or the simulator is unreachable.

2. Azure Monitor / Application Insights (new service)

• IaC (Iac/admin-webapp) provisions a dedicated Log Analytics workspace + Application Insights for the admin app.
• The SPA is instrumented with the App Insights web SDK: page views + custom events for every admin action (BotCreated, BotRecharged, BotServicingToggled, BotUpdated, BotDeleted).
• The connection string (a client ingestion key, not a secret) is fetched at build time from the IaC-provisioned resource via az and baked in — no data-plane RBAC / role assignment needed, so it's fully self-service.

Passwordless / IaC / Actions

• App Insights connection via client ingestion key; no secrets, no new role assignments.
• Provisioned by the consolidated iac.yml (PR = plan, merge = apply).
• Built + deployed via AdminWebpage-Deploy-WF.yml (OIDC).

Tests

• 26 unit tests pass (added telemetry-merge + App Insights config tests); build clean. App Insights SDK lazy-loads only when configured.

Notes for reviewers

• On merge, iac.yml creates the App Insights resource; the admin deploy then fetches its connection string. If the deploy races ahead of the apply on first merge, telemetry turns on at the next deploy (graceful no-op until then).

Relates to #18. Final feature (Option 1).
