[ci-bitrise] Mirror LC Wallet's bitrise.yml structure exactly

Switch from fastlane-driven build (build_app + hand-rolled apikey.json)
to Bitrise's own xcode-archive step, matching LC Wallet 1:1: manage-ios-
code-signing + xcode-archive@5 (automatic_code_signing: api-key) do the
build/sign, deploy-to-itunesconnect-deliver@2 handles TestFlight in the
beta workflow, fastlane only runs for the release lane (metadata push +
App Store upload) reading BITRISE_IPA_PATH — same shape as LC Wallet's
Fastfile beta/release lanes.

Only genuine differences from LC Wallet, all forced by this project's
actual layout:
- BITRISE_PROJECT_PATH/SCHEME point at Darwin/PediFoods.xcodeproj
- fastlane work_dir is Darwin/ (Fastfile lives there, not repo root)
- build number bumps CURRENT_PROJECT_VERSION in Skip.env instead of
  agvtool — this project has no VERSIONING_SYSTEM set, Skip.env is the
  actual shared source of truth for both Darwin and Android
- team_id comes from a DEVELOPMENT_TEAM secret instead of a hardcoded
  literal — LC Wallet's Apple team ID isn't necessarily this app's

Darwin/fastlane/Fastfile
