Chetan GowdaandGitHub 2312f6752f Prevent workflow task and activity task generation when workflow is paused (#8687) ...

## What changed?
- Prevents workflow task generation when paused (ex: signals, activity
completions, child workflow completions etc)
- Prevents activity task generation when a workflow is paused and an
inflight workflow task comes back with start activity commands.
- Prevents eager activity starts when the workflow is paused.

## Why?
When a workflow is paused, we should not generate any more new activity
and workflow tasks.

## How did you test it?
- [x] built
- [ ] run locally and tested manually
- [x] covered by existing tests
- [ ] added new unit test(s)
- [x] added new functional test(s)

> [!NOTE]
> Prevents workflow/activity task creation and certain API operations
when a workflow is paused, adds safeguards and tests across history,
NDC, and task refresh paths.
> 
> - **Behavior/State**:
> - Add `MutableState.IsWorkflowExecutionStatusPaused()` and honor
paused status across scheduling paths.
>   - `workflow/util.ScheduleWorkflowTask` returns early if paused.
> - **API Handlers**:
> - `RespondWorkflowTaskCompleted`: reject `ForceCreateNewWorkflowTask`
when paused; block eager activity and bypass activity task gen when
paused.
> - `SignalWithStartWorkflow`: do not schedule a new workflow task if
paused.
>   - `UpdateWorkflow`: reject updates while paused.
>   - Activity failure/respond paths: avoid new WFT when paused.
> - **NDC/Replication**:
> - Reapply events and buffered-event flusher: skip scheduling WFT if
paused.
> - `ndc.Workflow.FlushBufferedEvents`: don't schedule WFT when paused.
> - **Task Refresher**:
> - Skip refreshing WFT/activity tasks when paused; allow
timers/search-attr updates; skip close tasks for running/paused.
> - **Interfaces/Mocks**:
> - Add `IsWorkflowExecutionStatusPaused` to `MutableState` interface
and update mocks.
> - **Tests**:
> - New unit tests for paused behavior in handlers, NDC, task refresher,
and transfer queue; functional tests for pause/unpause workflow
behavior.
