🐘 feat: FerretDB Compatibility (#11769)
* feat: replace unsupported MongoDB aggregation operators for FerretDB compatibility

Replace $lookup, $unwind, $sample, $replaceRoot, and $addFields aggregation
stages which are unsupported on FerretDB v2.x (postgres-documentdb backend).

- Prompt.js: Replace $lookup/$unwind/$project pipelines with find().select().lean()
  + attachProductionPrompts() batch helper. Replace $group/$replaceRoot/$sample
  in getRandomPromptGroups with distinct() + Fisher-Yates shuffle.
- Agent/Prompt migration scripts: Replace $lookup anti-join pattern with
  distinct() + $nin two-step queries for finding un-migrated resources.

All replacement patterns verified against FerretDB v2.7.0.

* fix: use $pullAll for simple array removals, fix memberIds type mismatches

Replace $pull with $pullAll for exact-value scalar array removals. Both
operators work on MongoDB and FerretDB, but $pullAll is more explicit for
exact matching (no condition expressions).

Fix critical type mismatch bugs where ObjectId values were used against
String[] memberIds arrays in Group queries:
- config/delete-user.js: use string uid instead of ObjectId user._id
- e2e/setup/cleanupUser.ts: convert userId.toString() before query

Harden PermissionService.bulkUpdateResourcePermissions abort handling to
prevent crash when abortTransaction is called after commitTransaction.

All changes verified against FerretDB v2.7.0 and MongoDB Memory Server.

* fix: harden transaction support probe for FerretDB compatibility

Commit the transaction before aborting in supportsTransactions probe, and
wrap abortTransaction in try-catch to prevent crashes when abort is called
after a successful commit (observed behavior on FerretDB).

* feat: add FerretDB compatibility test suite, retry utilities, and CI config

Add comprehensive FerretDB integration test suite covering:
- $pullAll scalar array operations
- $pull with subdocument conditions
- $lookup replacement (find + manual join)
- $sample replacement (distinct + Fisher-Yates)
- $bit and $bitsAllSet operations
- Migration anti-join pattern
- Multi-tenancy (useDb, scaling, write amplification)
- Sharding proof-of-concept
- Production operations (backup/restore, schema migration, deadlock retry)

Add production retryWithBackoff utility for deadlock recovery during
concurrent index creation on FerretDB/DocumentDB backends.

Add UserController.spec.js tests for deleteUserController (runs in CI).

Configure jest and eslint to isolate FerretDB tests from CI pipelines:
- packages/data-schemas/jest.config.mjs: ignore misc/ directory
- eslint.config.mjs: ignore packages/data-schemas/misc/

Include Docker Compose config for local FerretDB v2.7 + postgres-documentdb,
dedicated jest/tsconfig for the test files, and multi-tenancy findings doc.

* style: brace formatting in aclEntry.ts modifyPermissionBits

* refactor: reorganize retry utilities and update imports

- Moved retryWithBackoff utility to a new file `retry.ts` for better structure.
- Updated imports in `orgOperations.ferretdb.spec.ts` to reflect the new location of retry utilities.
- Removed old import statement for retryWithBackoff from index.ts to streamline exports.

* test: add $pullAll coverage for ConversationTag and PermissionService

Add integration tests for deleteConversationTag verifying $pullAll
removes tags from conversations correctly, and for
syncUserEntraGroupMemberships verifying $pullAll removes user from
non-matching Entra groups while preserving local group membership.
