* feat: remove unused x-cal-timezone header and middleware matcher - Remove x-cal-timezone header setting from middleware.ts - Remove x-cal-timezone header setting from createNextApiHandler.ts - Remove /api/trpc/:path* from middleware matcher - Eliminates ~50M edge requests per month for unused functionality - All timezone handling uses browser detection and localStorage instead Co-Authored-By: keith@cal.com <keithwillcode@gmail.com> * update POST_METHODS_ALLOWED_API_ROUTES * test: remove api/trpc POST validation test - Remove test for /api/trpc/book/event POST requests since /api/trpc/:path* was removed from middleware matcher - Keep test for /api/auth/signup which is still processed by middleware Co-Authored-By: keith@cal.com <keithwillcode@gmail.com> --------- Co-authored-by: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Co-authored-by: hbjORbj <sldisek783@gmail.com>
