feat(aiturk): phone link for AITURK Mobil (1.0.0-beta.15)

Settings gets a Phone link window: when enabled, the IDE main process runs a
small TLS proxy on the local network (self-signed certificate, pinned by its
fingerprint) in front of the loopback backend and pairs a phone by QR code
or an 8-character code. Each phone gets its own revocable token; the backend
session token never leaves the computer. The root page, terminal sockets and
secret or settings-changing endpoints are not reachable from a phone. The
old WebRTC pairing window is replaced.
