fix: handle organizationUpdate duplicate start during unmerge (CM-852)

[skwowet]

Changes

• Switched from REJECT_DUPLICATE to ALLOW_DUPLICATE workflow reuse policy to allow starting new workflows after the previous one completed, failed, or was cancelled
• Added workflowIdConflictPolicy: FAIL to prevent concurrent workflows with the same ID
• Added pre-check to wait for running workflows before attempting to start a new one
• Renamed from recalculateActivityAffiliationsOfOrganizationSynchronous to recalculateActivityAffiliationsOfOrganizationAsync - no longer waits for the organization update workflow to complete, as organizations with many members can take some time to process
• Applied same changes to member affiliation workflows for consistency

Behavior

• If a workflow is already running, new triggers wait for it to complete before starting a new one
• If the previous workflow is in a terminal state (completed, failed, or canceled), a new workflow starts immediately
• Concurrent triggers collapse into a single follow-up run via conflict policy
• Ensures only one workflow per entity runs at any time

---

Note

Switch Temporal policies to allow reuse but fail conflicts, wait for running workflows, and make organization affiliation recalculation async, applying the same pattern to members and updating workflow callers/exports.

• Temporal workflow handling:
  • Use WorkflowIdReusePolicy.ALLOW_DUPLICATE with WorkflowIdConflictPolicy.FAIL for memberUpdate and organizationUpdate.
  • Pre-check existing handles; wait for RUNNING workflows before starting new ones; skip on WorkflowExecutionAlreadyStartedError.
• Organizations:
  • Rename recalculateActivityAffiliationsOfOrganizationSynchronous ➜ recalculateActivityAffiliationsOfOrganizationAsync and stop awaiting completion.
  • Update start args for organizationUpdate unchanged; introduce conflict/reuse policies and pre-check logic.
• Members:
  • Apply identical conflict/reuse policies and pre-check logic to recalculateActivityAffiliationsOfMemberAsync.
• Workflows and exports:
  • Update imports/exports and workflow calls to use recalculateActivityAffiliationsOfOrganizationAsync during unmerge.
  • Central activities.ts reflects renamed org function.
