fix(navigation): remove legacy desk fixtures

[harshtandiya]

Summary

• remove the legacy Workspace Sidebar fixture
• remove the dependent Desktop Icon fixture
• rely on Frappe generated module navigation and the existing add_to_apps_screen hook

Context

Frappe develop fails while converting the legacy Buzz sidebar because its title is Buzz, its module is Events, and Buzz is also a registered module name. Removing the retired fixtures avoids that invalid conversion path.

Verification

• pre-commit checks passed
• git diff --check passed
• confirmed no remaining Workspace Sidebar or Desktop Icon references in Buzz source

Greptile Summary

Removes the legacy Buzz Workspace Sidebar and its dependent Desktop Icon fixture so Frappe uses the modern generated navigation mechanisms instead.

• Retains the public Buzz Workspace for Desk navigation.
• Retains the Buzz apps-screen entry, including its permission check and /b route.
• Removes the invalid legacy sidebar conversion path described by the PR.

Confidence Score: 5/5

The PR appears safe to merge because it removes only legacy navigation fixtures while retaining the supported Buzz Workspace and apps-screen registration.

No concrete behavioral, security, or repository-rule violation remains after verifying the supported Frappe range and the retained navigation configuration.
