fix: apply request macros to every incoming request in enhanceRequest

`requestMacroRegistry` defines `bearerToken()`, `input()`, `has()`,
`missing()`, `filled()`, `only()`, `except()`, `wantsJson()`, `isAjax()`,
`ip()`, `userAgent()`, `header()`, etc. — but `applyMacros()` was never
called from the live request flow. Macros only attached when callers
manually invoked `RequestHelpers.withMacros(req)` or `RequestHelpers.create(...)`.

Effect: middleware and handlers calling `request.bearerToken()` etc. blew up
with `TypeError: request.bearerToken is not a function` because the macros
weren't on the request. Reproduced with the Stacks `Auth` middleware pulling
the bearer token off an authenticated request.

Fix: call `RequestWithMacros.applyMacros(enhancedReq)` inside `enhanceRequest`
right before the cookie utility is attached. Macros run first; the cookie
utility object then overrides the `cookies` macro (the macro returns a plain
record while consumers expect the get/set/delete object form).

All 359 existing tests pass.
