feat(notifications): add auto top-up notification for organization owners (#970)

## Summary

Adds a new `generateAutoTopUpOrgsNotification` notification generator
that promotes the auto top-up feature to organization owners. The
notification is only shown to users who have `'owner'` role in at least
one organization, using the existing `getUserOrganizationsWithSeats`
function to check membership roles. Wired into the existing
`generateUserNotifications` aggregation alongside the other conditional
generators.

## Verification

- [x] `pnpm typecheck` — passes cleanly, no type errors

## Visual Changes

N/A

## Reviewer Notes

- The `OrganizationRole` type is `'owner' | 'member' |
'billing_manager'` — there is no `'admin'` role in the schema, so the
check filters on `role === 'owner'` only, which is the admin-equivalent
role for organizations.
- The function reuses the existing `getUserOrganizationsWithSeats`
import already present in the file (used by
`generateAutoTopUpNotification` and `generateKiloPassNotification`).
