Fix duration mockapi float comparisons to be numeric

[SergioChan]

Summary

• switch duration query float scenarios to dedicated handlers that compare numeric values via Number(req.query?.input)
• switch duration header float scenarios to dedicated handlers that compare numeric values via Number(req.headers?.duration)
• keep integer/string scenarios unchanged so the diff stays scoped to the float comparison bug in the issue

Testing

• pnpm prettier --check packages/http-specs/specs/encode/duration/mockapi.ts
• attempted to run pnpm --filter @typespec/http-specs exec tsp-spector validate-mock-apis ./specs/encode/duration, but this isolated run is missing built @typespec/spec-api artifacts required by tsp-spector (ERR_MODULE_NOT_FOUND from packages/spector/dist/...)

Thanks for the heads-up. I pushed a follow-up commit adding the required Chronus changeset for @typespec/http-specs.
