fix(web): preserve checkout when opening project settings

[msegec]

What Changed

Opening Project settings from a thread now selects that thread's environment and physical checkout. Project-group actions remain group-wide. Settings also uses the sidebar's representative instead of selecting the first connected checkout.

Why

Two checkouts of the same repository can have different icons and defaults. Thread actions previously discarded the checkout before navigating, so Settings could display and edit another copy. The shared navigation helper preserves environment/path identity across the sidebar, legacy sidebar, thread menu, draft view, and contextual command palette, including duplicate project records.

Validation

• Eight focused navigation and settings tests pass. Restoring the old behavior makes three regressions fail.
• Web typecheck passes; focused new-file lint passes with warnings denied.
• Independent checks exercise the actual Sidebar and command-palette callbacks, including historical duplicate IDs and offline representatives.
• Integrated browser verification passed against an isolated fleet build with two copies of the same repository: the gold checkout previously opened group-wide settings showing default blue and a fallback icon; after the fix it opens its own settings with the loaded icon and gold accent. Saving changed only the selected checkout, preserving the other copy and its icon path.
• The fleet-only accent editor is used as a visible diagnostic; it is not part of this upstream change. Screenshots and an interaction recording were captured locally; attachment upload was unavailable in the signed-out browser.

📝 Walkthrough

Walkthrough

Project settings entry points now preserve environment and checkout context through search parameters. Grouped project settings use a shared representative-selection helper. Tests cover duplicate, remote, and unscoped projects. Documentation describes the updated selection and icon behavior.

Merge Risk: 🟡 Moderate · up to 4697c

Opening Project settings from the legacy sidebar’s project header can still select or modify a different checkout in a grouped project. This should be corrected before merge so all settings entry points preserve checkout context.

1747-1753: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Pass the project header’s checkout context to project settings.

The "project-settings" handler passes only project.projectKey to the legacy route. That route redirects with machine and checkout unset, so grouped projects can lose the header’s intended checkout context. Navigate directly to /settings/projects with projectSettingsSearch(project.projectKey, projectSettingsRepresentative(project)).

Closing under the verification rule. The PR says the before/after screenshots and interaction recording remain local. Please attach them or link an accessible copy showing the correct checkout opening and only that checkout changing on save, then request reconsideration.
