Adds experimental, opt-in Apple Silicon iOS simulator configuration while keeping normal device builds on staging's released dependencies.

Set STACK_IOS_SIMULATOR=1 when configuring the ios target. Stack Wallet enables the review-pinned Monero and Wownero simulator packages; Stack Duo enables only Monero. Other platforms and ordinary iOS configuration keep their released dependencies and the staging lockfile. The CocoaPods arm64 simulator architecture selection remains.

The earlier submodule/MWEB overrides and build instructions were partly superseded by Flutter Native Assets. Documentation now describes the current setup, opt-in usage, and its limits.

The six original prerequisite PRs are all closed without merging:

Prerequisite	Current status
frostdart #26	Superseded by the native-assets migration (#27).
flutter_libepiccash #84	Closed as unnecessary after migration to native assets.
flutter_libmwc #10	Superseded by #11.
flutter_mwebd #1	Superseded by #2.
cs_monero #23	Closed, unmerged; experimental simulator override remains review-pinned.
cs_wownero #1	Closed, unmerged; experimental simulator override remains review-pinned.

Not release-ready: these simulator pins predate the current device-library ABI. The Monero pin lacks MONERO_Wallet_serializeCacheToJson, exported by the current device package. Stack does not currently call that symbol, but the mismatch still requires refreshed simulator libraries and macOS linking/wallet smoke tests. Linux configuration checks do not establish a working iOS simulator build.

Validation: 12 regression cases invoke the actual Wallet/Duo configure scripts and template/interface processors across default, disabled, enabled, and non-iOS scenarios. Scoped Dart analysis reports no issues; Bash syntax and Ruby Podfile syntax pass. pubspec.lock is identical to staging, obsolete crypto-plugin gitlinks remain removed, and git diff --check passes. Both remotes contain the same refreshed commit.

This whole PR is being superceded by the alternative slate of native-assets migrations which make these changes unnecessary. gg

a small portion of this may still be required. Will reopen just for reference
