chore: antd button -> signozui button migration

Orval v8's pre-generation validator (@scalar/openapi-parser) treats every
`$ref` key as a JSON Reference. Our spec embeds Perses' `common.JSONRef`
struct, which has a property literally named `$ref`, so validation aborts
with `INVALID_REFERENCE`. Set `input.unsafeDisableValidation: true` to
bypass — codegen itself handles the spec correctly, and the spec is
backend-generated and CI-gated.

Closes SigNoz/engineering-pod#4963
