Add documentation for sync template throttling and performance issues

[Copilot]

Admin sync flows (v3 Flow Action Details, v4 Flows) running 7+ hours instead of <1 hour due to API throttling from concurrent executions. Root cause: Driver updates trigger 20+ child flows simultaneously; without delay settings, creates 1000+ concurrent API calls exceeding Dataverse limits (6K req/5min), forcing retry cascades with exponential backoff.

Changes

Core Documentation

• TROUBLESHOOTING-SYNC-PERFORMANCE.md - Comprehensive guide covering symptoms, root causes, 6 solution strategies, performance benchmarks by tenant size, and advanced troubleshooting
• ISSUE-ANALYSIS-SYNC-PERFORMANCE.md - Technical analysis of cascading trigger pattern, concurrency settings (repetitions: 50 in loops), and throttling behavior

User Guidance

• ISSUE-RESPONSE-SYNC-PERFORMANCE.md - Response template for similar issues with expected performance tables and follow-up steps
• Updated Core Components README, troubleshooting directory README, and main README with links to new guides

Solution

Enable environment variables:

• admin_DelayObjectInventory = Yes (adds 0-2s random delays in object inventory)
• admin_DelayInventory = Yes (spaces out environment processing in Driver)

Expected Performance (delays enabled, incremental mode):

• Small (<500 flows): 10-20 min
• Medium (500-2K flows): 30-60 min
• Large (2K-10K flows): 1-2 hrs
• Enterprise (10K+ flows): 2-4 hrs

Technical Details

Flow architecture creates multiplicative concurrency:

Driver → updates admin_environment table
  ↓
Triggers 20+ flows via Dataverse webhook (message: 4, scope: 4)
  ↓  
Each flow: foreach with concurrency.repetitions: 50
  ↓
Result: 20 × 50 = 1000+ concurrent API calls → throttling → retries → 7+ hour runtime

No code changes required. Configuration issue, not bug.

<issue_description>### Does this bug already exist in our backlog?

• I have checked and confirm this is a new bug.

Describe the issue

Admin | Sync Template v3 (Flow Action Details) in this for some environments it is in Running state for long more than 7 hrs.
Also the
Admin | Sync Template v4 (Flows) . Both are triggered on the environment table change and might be that is causing the throttle..

Expected Behavior

Should complete the flow in max 1 hour-...as before
