Subject: [PATCH] feat: add manual speech mode switch (Auto/Browser/Server)

- Added Mic Mode selector in consult header
- Apply one preference to both Complaints Mic and Med Mic
- Browser mode can be forced to bypass /stt-proxy 400 errors
- Preference persisted in localStorage
- Mode change stops active recordings safely before applying
