fix: build number 1 -> 2, and stop xcodegen silently resetting it

CFBundleVersion/CFBundleShortVersionString weren't declared in
project.yml's properties block, so xcodegen defaulted them to "1"/"1.0"
on every regenerate regardless of CURRENT_PROJECT_VERSION/
MARKETING_VERSION — bumping the build setting silently did nothing.
Declared both explicitly (matching how CFBundleIdentifier and
CFBundleExecutable already reference build settings), so version bumps
now actually reach the compiled app. Verified: CFBundleVersion "2" in
the built binary's Info.plist.
