fix: broken Firebase auth gate in API layer

waitForAuthInitialization was silently passing through without
waiting. authStore.isInitialized is unwrapped by Pinia (plain
boolean, not a ref), and until() without .toBe() returns a
builder object, not a promise — so Promise.race resolved
immediately.

Fix with storeToRefs to preserve the ref and .toBe(true) to
get an actual promise.
