fix(auth): type-check its tests (#4040 tranche 1)

[yinlianghui]

Part of #4040 — tranche 1, package 2 of 5. One package per PR, per the 裁决 on objectstack-ai/objectstack#4118 (PM, 2026-08-03):

小包先行,core(80)/react(76)最后;
每包独立 PR;守卫类 PR 必须附 pre-fix 代码报红的运行记录(判别力证明,防「绿灯守卫从未真正跑过」——已发现的第三种失败模式:tsconfig.test.json 存在但没人跑);
TEST_DEBT 条目随包清零,只减不增。

Before:

src/__tests__/AuthProvider.test.tsx(15,3): error TS2322: Type '{ signIn: ((credentials: SignInCredentials) => Promise< { user: AuthUser; session: AuthClientSession; } >) | Mock< ... >; ... 37 more ...; listUserInvitations?: (() => Promise< AuthInvitation[] >) | undefined; }' is not assignable to type 'AuthClient'.
Types of property 'sendVerificationEmail' are incompatible.
Type '((email: string, callbackURL?: string | undefined) => Promise< void >) | undefined' is not assignable to type '(email: string, callbackURL?: string | undefined) => Promise< void >'.
Type 'undefined' is not assignable to type '(email: string, callbackURL?: string | undefined) => Promise< void >'.
src/__tests__/createAuthClient.test.ts(154,33): error TS6133: 'input' is declared but its value is never read.

Both were real code-tier defects — nothing reclassified as config here.

1. A mock that claimed to be an AuthClient and was not

createMockClient is annotated : AuthClient and implements 8 of that interface's ~38
methods. The double itself is the right call — AuthProvider reaches only those 8 on the
paths under test, and stubbing thirty unreached methods would be noise. The claim was
not: an unchecked test asserting a type it does not satisfy is precisely the "reads as
evidence" failure #4040 is about.

Resolved the way this package's three other mock-client factories already do it —
LoginForm.test.tsx:36, identifier-trim.test.tsx:29, SocialSignInButtons.test.tsx:29
all end } as unknown as AuthClient;. AuthProvider.test.tsx was the one that predated
the convention. No public type changed, and no method was stubbed to make an assertion
pass.

2. TS6133 on an unread fetch-double parameter

noUnusedParameters is on repo-wide; _input is the sanctioned spelling.

Discrimination proof — the new project can fail

A tsconfig.test.json that exists but compiles nothing is the objectui#3009 shape and the
third failure mode the 4118 thread names, so the new project itself is what needs its
discrimination shown. Appending a provably-false line to src/__tests__/AuthProvider.test.tsx
and re-running:

$ npx tsc -p tsconfig.test.json
src/__tests__/AuthProvider.test.tsx(331,7): error TS2322: Type 'string' is not assignable to type 'number'.
EXIT:2

Reverted immediately; the probe is not in the diff.

Note on the existing narrow project

tsconfig.typetests.json (objectui#3181) compiles auth-spec-parity.test.ts alone — the
rescue for a package whose whole test tree was in debt. It stays chained and now overlaps
the full project, at the cost of one extra compile of one file. Retiring the narrow
projects once their package leaves TEST_DEBT is a real cleanup but it is not this
tranche's scope, and it is reported to the PM as a finding rather than smuggled in here.

Verification

$ pnpm --filter @object-ui/auth type-check
> tsc --noEmit && tsc -p tsconfig.typetests.json && tsc -p tsconfig.test.json
EXIT:0
$ pnpm exec vitest run packages/auth --maxWorkers=2 # from the repo root, per objectui#3378

TEST_DEBT shrinks by exactly this package's line; no other entry is touched.
