fix(tlon): Fix Zod v4 record() and @urbit/aura v3 API changes (#1631)

* fix(tlon): Fix Zod v4 record() and @urbit/aura v3 API changes

- Fix Zod v4.3.6 bug: single-arg z.record() fails with toJSONSchema()
  - Use two-arg form: z.record(z.string(), schema)
  - Fixes 'Cannot read properties of undefined (reading _zod)' error

- Fix @urbit/aura v3.0.0 API migration:
  - unixToDa() → da.fromUnix()
  - formatUd() → scot('ud', ...)
  - Fixes '(0 , _aura.unixToDa) is not a function' error

These were blocking Tlon plugin loading and outbound messaging.

* fix: add tlon schema/aura tests (#1631) (thanks @arthyn)
