feat: bind a browser sign-in to the browser that started it, so a handoff link cannot be forwarded: one-time state proves the callback answers a request this server made, not one THIS browser made, so anyone could run the flow against their own Google or OIDC account and send the resulting URL to someone else, whose browser would then hold the sender's session (RFC 9700 4.7.1); begin now mints a binding secret that never reaches the provider and never appears in a URL, the callback carries it into the handoff, and the exchange refuses a collection that cannot present it with sso_wrong_browser, while the comments this PR added are condensed to the constraint they exist to state

feat: build the browser half of social sign-in, which was never wired: GOOGLE_CLIENT_ID was read at boot and made the login screen render a Google button, but the button opened a popup at /auth/google/login which no route served, and authService.GoogleAuth/AppleAuth had no caller anywhere in the codebase; internal/app/socialauth now runs Google and Apple through the flow generic OIDC already used (one-time state, PKCE, nonce, id_token verified against the provider JWKS, identity keyed on issuer and subject, JIT provisioning, the ban and 2FA gates), the redirect URI defaults to API_PUBLIC_URL/v1/auth/<provider>/callback and is logged at boot because registering the dashboard origin instead is the mistake that produces a valid OAuth client and a dead button, /auth/config advertises only providers the backend can actually complete, the SSO landing page no longer swallows a two_fa_required response, and OIDC_PROVIDER_NAME finally reaches the button it documents
