Render managed auth field input modes

[masnwilliams]

summary

• preserve optional canonical field input_mode values in the existing UI model
• apply the hint through React’s inputMode prop while keeping identifier inputs as type="text"
• retain compatibility with API events that omit the new field

dependencies

• depends on Render generic identifiers as text inputs #28, which keeps canonical identifiers free of browser-native format validation
• merge after kernel/kernel#3693 is deployed; older API responses remain compatible but do not carry input modes
• kernel/managed-auth-agent#87 begins emitting host-observed hints

testing

• bun test
• bun run build
• bun run typecheck
• bun run format:check

Note

Low Risk
Auth form input typing and autofill hints only; behavior is more permissive for identifiers and remains backward compatible when input_mode is omitted.

Overview
Adds optional canonical input_mode on managed auth fields and threads it through session normalization into DiscoveredField, exporting the new InputMode type from the package.

Identifier fields are no longer mapped to type="email" or type="tel" from ref; they render as type="text" so combined login fields (e.g. “mobile, username, or email”) are not subject to browser-native format validation. Hints come from React’s inputMode prop instead, with autoComplete driven by input_mode for dedicated email/phone fields while mixed identifiers with input_mode: "text" skip inferred email autofill. One-time-code fields still take one-time-code over keyboard hints.

Tests cover autocomplete precedence, mixed-identifier behavior, and that email hints use inputMode="email" with type="text".

reviewed — lgtm, approve. two non-blockers:

• packages/managed-auth-react/src/components/UnifiedAuthForm.test.ts — worth adding a test pinning the ordering: input_mode should take precedence over the ref-based username heuristic (e.g. ref: "username" + input_mode: "email" → "email"), so the precedence is deliberate rather than emergent
• packages/managed-auth-react/src/session/state.ts:68 — nit: ...(field.input_mode ? { input_mode: field.input_mode } : {}) can just be input_mode: field.input_mode since the prop is already optional
