The plan's share feature for the (single-config) desktop GUI. The QR is
rendered locally so the access key never leaves the device.
- src-tauri: add `qrcode = "0.14"` (features=["svg"]) + `generate_qr`
command (string -> SVG), registered in the invoke handler. Ported from
the current ostp-gui. (cargo check on src-tauri passes.)
- Frontend: "Share" button next to Import builds `ostp://KEY@HOST?sni&type`
from the current config fields, calls generate_qr, and shows a modal with
the QR + a read-only link + Copy. Added i18n keys (en/ru) so the new
data-i18n labels resolve (missing keys would render as the raw key).
Note: Rust side verified via cargo check; the frontend is syntax-checked
(node --check) but not runtime-verified — needs a Tauri build to confirm
visually.
