chore(shadcn): silence TS 6 baseUrl deprecation in tsconfigs

The previous commit added baseUrl so the shadcn-vue CLI's
resolvedPaths validator passes. TypeScript 6 emits a deprecation
error for baseUrl (slated for removal in TS 7); vue-tsc treats it as
a hard build failure.

Per the upstream guidance ('Specify compilerOption
"ignoreDeprecations": "6.0" to silence this error'), suppress the
deprecation in both tsconfig.json and tsconfig.app.json. Revisit
when shadcn-vue's CLI migrates off baseUrl.
