692-700: Extract duplicated throttle piping into one helper.The same conditional throttle/piping and abort cleanup logic is repeated across multiple paths. Centralizing it will reduce drift and future bugs.

In `@application/src/frontend/views/ClientOptionsView.svelte`:
- Around line 93-96: The UI uses "MB/s" but the backend uses binary MiB
(1024*1024) units—update the UI to use consistent binary units: change the
setting's displayName and description in ClientOptionsView.svelte (the object
with keys displayName, description, defaultValue) to reference "MiB/s" (or
explicitly "MiB/s (1024*1024 bytes/s)") and adjust the explanatory text
accordingly (e.g., "Maximum download speed for direct downloads in MiB/s. Set to
0 for unlimited.") so the label matches the backend conversion.
