feat: Implement console session management with tenant and profile handling

- Add ConsoleSessionStore for managing console session state including tenants, profile, and token information.
- Create OperatorContextService to manage operator context for orchestrator actions.
- Implement OperatorMetadataInterceptor to enrich HTTP requests with operator context metadata.
- Develop ConsoleProfileComponent to display user profile and session details, including tenant information and access tokens.
- Add corresponding HTML and SCSS for ConsoleProfileComponent to enhance UI presentation.
- Write unit tests for ConsoleProfileComponent to ensure correct rendering and functionality.

 ### 1.1 MongoDB validators
 
 - Apply JSON schema validators to `advisory_raw` and `vex_raw` collections before enabling AOC guards.
+- Before enabling validators or the idempotency index, run the duplicate audit helper to confirm no conflicting raw advisories remain:
+  ```bash
+  mongo concelier ops/devops/scripts/check-advisory-raw-duplicates.js --eval 'var LIMIT=200;'

+1. **Duplicate audit:** Confirm `mongo concelier ops/devops/scripts/check-advisory-raw-duplicates.js --eval 'var LIMIT=200;'` reports no conflicts before restarting Concelier with the new migrations.
+2. **Post-migration check:** After the service restarts, validate that `db.advisory` is a view pointing to `advisory_backup_20251028`:
+   ```bash
+   mongo concelier --quiet --eval 'db.getCollectionInfos({ name: "advisory" })[0]'
+   ```
+   The `type` should be `"view"` and `options.viewOn` should equal `"advisory_backup_20251028"`.
+3. **Supersedes chain spot-check:** Inspect a sample set to ensure deterministic chaining:
+   ```bash
+   mongo concelier --quiet --eval '
+     db.advisory_raw.aggregate([
+       { $match: { "upstream.upstream_id": { $exists: true } } },
+       { $sort: { "tenant": 1, "source.vendor": 1, "upstream.upstream_id": 1, "upstream.retrieved_at": 1 } },
+       { $limit: 5 },
+       { $project: { _id: 1, supersedes: 1 } }
+     ]).forEach(printjson)'
+   ```
+   Each revision should reference the previous `_id` (or `null` for the first revision). Record findings in the change ticket before proceeding to production.
