Add WHIP ingest toggle to Edit page with _upsertProcess patch

- Import WHIPControl from misc/controls/WHIP
- Render WHIPControl bound to control.whip_ingest before the WHEP section
- Monkey-patch props.restreamer._upsertProcess in handleDone so that
  whip_ingest.enabled is injected into the main ingest process config
  before it reaches the Core API. The SDK's UpsertIngest does not
  forward control.whip_ingest, so this intercept is required.
- Note: enable (no trailing d) is used in UI state to match WHEP.js convention;
  it maps to enabled (with d) in the Core API JSON body.
