Subject: [PATCH 1/2] fix: add has trap to lazy auth proxy so auth routes
 resolve handler

The lazy `auth` Proxy only trapped `get`, leaving `has` to forward to its
empty target. better-auth's `toNextJsHandler` checks `"handler" in auth`
per request; that returned false, so it fell through to calling
`auth(request)`, which isn't callable. Result: every /api/auth/* POST threw
"TypeError: ... is not a function" in production (e.g. sign-in/social).

Add a `has` trap forwarding to the real instance. Stays build-time safe: the
check only runs inside toNextJsHandler's per-request closure, never at module
load, so env-validation decoupling is preserved.

Subject: [PATCH 2/2] fix: type lazy proxy get-traps to satisfy no-unsafe lint

The get-traps assigned `Reflect.get(...)`'s `any` return, tripping
@typescript-eslint/no-unsafe-{assignment,return,call,member-access} (12
errors, pre-existing red on main since the proxies landed). Annotate the
forwarded value as `unknown` and cast on the function branch so binding is
type-checked. Runtime behavior is unchanged.
