chore(showcase): seed Field Zoo with all field types + guard budget hook (#2005)

The Field Zoo declared all 48 field types but shipped NO seed data, so no
field type was ever exercised with a real value — which is exactly why the
array-serialization and Field.time bugs (fixed in #2004) went unnoticed.

- Seed two field-zoo specimens ("Full" + "Minimal") covering every input-able
  field type with real values: arrays (multiselect/checkboxes/tags/repeater/
  vector), objects (composite/address/location/json/record), time (14:30 /
  09:05:30), relational (lookup→Account, master_detail→Project by externalId),
  and computed (formula=315, autonumber). `f_secret` is intentionally omitted —
  the seed path has no CryptoProvider so a secret value is refused fail-closed.
  This doubles as a runtime regression guard: a field type that can't persist
  now fails the boot seed instead of shipping silently.
- Guard the showcase_warn_over_budget hook condition with has() — a partial
  rollup update (task_count recompute) fires afterUpdate with a record lacking
  spent/budget, and CEL throws "No such key" on a bare record.spent. has() is
  the missing-key-safe macro; the noisy warning is gone.

Verified live: both specimens seed (37 populated f_* fields on Full); coverage
test 20 green; warn_over_budget "No such key" warnings = 0 after a task update.

+chore(showcase): seed the Field Zoo with two specimens exercising every input-able field type (arrays/objects/time/relational/computed all populated), and guard the `warn_over_budget` hook condition with `has()` so a partial rollup update no longer logs a "No such key" warning. The seed doubles as a runtime regression guard for the field-type persistence fixes — a field type that can't store now fails the boot seed instead of shipping silently. Example-app only; no package impact.
