fix(assets): remove invalid strict option from UnpluginTypia config

`@ryoppippi/unplugin-typia` Options type doesn't have a `strict` field
(I confused it with typia core's strict validators). The PR-2 CI
template-build job caught this with TS2353 in next.config.ts:32 and
vitest.config.ts:19 — exactly the kind of regression the new job was
designed to find. Working as intended.

next.config.ts: keep `cache: true`.
vitest.config.ts: pass no options (auto-detects typia.* calls).
