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
UI and autofill hinting only; behavior is covered by new unit tests and remains backward compatible when API omits input_mode.

Overview
Adds optional canonical input_mode (text | email | tel | numeric) on managed-auth fields, carries it through session normalization into DiscoveredField, and wires it to React inputMode on UnifiedAuthForm inputs while identifier fields stay type="text" so browsers do not apply email/tel format validation.

getAutocomplete now uses input_mode for dedicated email/tel autofill, keeps one-time-code ahead of tel hints on code fields, and avoids inferring email autofill when a mixed identifier uses input_mode: "text". InputMode is exported from the package; a patch changeset documents the behavior.

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
