Add Swift CodeQL workflow and fix Dependabot config

[Copilot]

CodeQL for Swift was missing, and Dependabot config failed due to an empty package ecosystem.

• Security scanning: Add macOS CodeQL workflow that builds both iOS and macOS targets with signing disabled, using a shared CodeQL config scoping analysis to ios/ and mos/.
• Configuration: Add .github/codeql/codeql-config.yml for Swift paths; fix .github/dependabot.yml to monitor GitHub Actions weekly.

Example (CodeQL workflow build step excerpt):

xcodebuild build \
  -project Flean.xcodeproj \
  -target Flean \
  -configuration Debug \
  -sdk iphonesimulator \
  -skipPackagePluginValidation \
  CODE_SIGNING_ALLOWED=NO \
  CODE_SIGNING_REQUIRED=NO \
  CODE_SIGN_IDENTITY=""

No clue what this means

I guess we will have to wait and see when automerge eventually gets to it.

For some reason this will not merge
