Stefano Demiliani 8373bc4717 fix(community/performance): correct httpclient and oncompanyopen good samples
httpclient-inside-write-transaction-holds-locks.good.al
- Pass Customer.RecordId as the last argument to CreateTask so the task
  is bound to the single customer that was written, not to all customers.
- Declare TableNo = Customer on the task codeunit so the platform loads
  the bound record into Rec automatically when OnRun executes.
- Replace the FindSet loop over all customers with Rec."No.", preserving
  the one-customer scope of the original SyncCustomerLastName procedure.

- Replace Session.GetCurrentClientType() with Session.CurrentClientType(),
  the correct platform method name.
- Fix the idempotency check: TaskScheduler.TaskExists() requires a Guid,
  not a codeunit integer ID. Store the Guid returned by CreateTask in
  IsolatedStorage (DataScope::Company) under a fixed key; on the next
  login read it back as Text, Evaluate it to Guid, and pass that Guid to
  TaskExists so the type matches the method signature.
