Show new server drafts in the macOS sidebar

[austin-smith]

What Changed

• Represent new macOS servers as selectable draft rows with names that update as the form is edited.
• Restore the previous server selection on cancellation, with safe fallback when that server is gone, and allow cancelling the first server draft.
• Add four navigation regression tests and document signed-build requirements for manual testing.

Why

The new-server form previously appeared without a matching sidebar selection, making it unclear which server was being edited. Drafts now appear immediately while persistence still happens only after a successful save.

UI Changes

• Show a selected New Server row with an Unsaved subtitle, updating its name as the user types.
• Disable the add button while a draft is open; remove the draft on cancellation and select the saved server after creation.
• Preserve discard confirmation when navigating away from an edited draft, and hide the empty-list message while a draft is visible.

Validation

• macOS test suite: 229 tests passed, including four new navigation regression tests.
• iOS unsigned compile check passed; SwiftLint and git diff --check passed.
• Structured code review found no actionable blockers.
• Manually verified draft selection, live name changes, validation failure, cancellation, and starting a fresh draft.
• Built macOS with normal Apple Development signing in isolated DerivedData; strict deep signature verification passed, and the app launched with the saved server connected.
