chore(ios): bump marketing version to 0.1.2

Related issue

N/A — release chore.

Summary

• Bumps MARKETING_VERSION from 0.1.1 to 0.1.2 for the ai.omnigent.ios target
  (Debug and Release) ahead of a TestFlight build, so testers can tell the build
  carrying the workspace fixes apart from earlier 0.1.1 uploads.
• Covers two user-facing iOS fixes now on main: connecting to a Databricks
  workspace opens Omnigent directly and hides the workspace nav bar (fix(ios): land Databricks workspaces on /omnigent and hide the workspace chrome #4559), and
  the top controls no longer render under the status bar on workspace-hosted
  servers (fix(ios): keep viewport-fit=cover when the workspace host rewrites the viewport #4568).
• Only the app target moves. The .tests / .uitests bundles stay at 0.1.0 —
  they are never shipped, and web/ios/RELEASE.md scopes manual bumps to the
  Omnigent target.
• CURRENT_PROJECT_VERSION is deliberately untouched: the beta lane computes
  the build number as latest_testflight_build_number + 1 and injects it via an
  xcodebuild override, so bumping it in git would only add churn.
• Not part of the repo-wide version lockstep: scripts/update_versions.py covers
  the Python packages and the Electron desktop app, not the iOS project.

Test Plan

• xcodebuild -project web/ios/Omnigent.xcodeproj -target Omnigent -showBuildSettings -configuration Release reports MARKETING_VERSION = 0.1.2
  and PRODUCT_BUNDLE_IDENTIFIER = ai.omnigent.ios, confirming the resolved
  setting rather than just the edited text.
• python scripts/update_versions.py check is unaffected (iOS is not one of the
  locked locations).
• pre-commit run --files web/ios/Omnigent.xcodeproj/project.pbxproj clean.

Coverage notes

Build-setting metadata with no runtime behaviour, so there is nothing to unit
test. Verified by reading back the resolved MARKETING_VERSION from
xcodebuild -showBuildSettings for the Release configuration of the shipping
target.
