BillingPage's data fetch was gated on `userRole`, a $state seeded by
`{@const _ = (userRole = user.role)}` inside the AdminShell snippet's
template. Svelte 5 treats $state writes during render as
state_unsafe_mutation and the parent's $effect did not re-fire — so
load() never ran, /billing/admin/promos and /billing/admin/settings
were never called, and the inner spinner sat forever on
admin.openova.io/nova/billing.
Replace the cross-component reactivity coupling with BillingPage's own
getMe() inside its initial $effect (mirrors RevenuePage). Drop the
@const assignment from the snippet. Existing save/upsert/delete
handlers still use `userRole` for post-mutation reload and now read
the value seeded by the initial effect — same end state, no behaviour
change for the working sections.
