Capacitor 8 — Step B: migrate iOS from CocoaPods to Swift Package Manager

Move off CocoaPods (sunsetting; trunk goes read-only Dec 2026) to SPM, the Cap 8
default. This also ends the LiveKit git-pin hack — LiveKit becomes a real SPM dep.

- Each local plugin gets a Package.swift (swift-tools 5.9, iOS 15, capacitor-swift-pm
  from 8.0.0, source path ios/Sources/<Plugin>). native-call additionally declares
  LiveKit: .package(client-sdk-swift, exact 2.15.3) + product "LiveKit".
- native-call Swift: import LiveKitClient -> import LiveKit (SPM product name).
- codemagic.yaml: `cap add ios --packagemanager SPM`; removed the "Install CocoaPods"
  (pod install) step; XCODE_WORKSPACE -> XCODE_PROJECT (App.xcodeproj); build-ipa
  --workspace -> --project. Xcode resolves the Swift packages during archive.
- ios-patch.sh: removed the Podfile LiveKit git-pin injection + Podfile.lock deletion
  (no Podfile under SPM). Info.plist/entitlements/AppDelegate/notif.wav patches stay.
- add-share-extension.rb is SPM-safe (operates on App.xcodeproj, no workspace/Pods refs).

Authored blind (no local Xcode) — expect build iterations on the first SPM build
(cap-add SPM layout, CapApp-SPM plugin wiring, LiveKit SPM resolution, signing).
Fully revertible: git revert -> back to Cap 8 + CocoaPods (working).
