build(apple): stop tracking generated localization outputs

Localizable.xcstrings and Generated/L10n.swift are generated from
localization/strings.json — the single source of truth — yet were committed,
which caused redundant tracking and a spurious ~10k-line diff every time
Xcode reformatted the catalog on build.

Treat them like the (already gitignored) Rust bindings: generate at build
time instead of tracking them. gitignore both; make the `apple-project`
target depend on `localization` so `bun run generate` recreates them before
xcodegen; install Bun in the Apple CI job and trigger it on localization/**.
Android strings.xml stays tracked — it has no reformatting churn and its
build doesn't run the generator.
