ci: update iOS workflow to use macOS 14 runner (#1064)

* Update iOS CI workflow to use macOS 14 runner

* Add `--break-system-packages` flag and remove redundant pip upgrade in iOS CI post-clone script.

* Set up iPhone 16 Pro simulator in iOS CI workflow

* Fix defaults command in iOS CI simulator setup script to correctly set `CurrentDeviceUDID` and add fallback warning

* Improve backend description layout in BenchmarkConfigSection to support text overflow handling
