Decouple clocking from teams and streamline timesheet rows

[mfisher31]

Closes #214 by removing direct team association on ClockEvent. e.g. Agnostic clock in/out.

• Remove team-scoped clock API requirements for start/stop/pause/resume/status/manual flows.
• Make ClockEvent.teamId optional for legacy compatibility while shifting active-session behavior to user scope.
• Simplify clock websocket updates to authenticated user streams and update frontend consumers accordingly.
• Drop Team column rendering from timesheet tables and update related row components/tests.
• Align backend, frontend, and e2e tests with the new user-scoped clock contract.

Pull request overview

This PR decouples clock events from team-scoped behavior so clocking in/out operates at the authenticated-user level, while preserving optional teamId compatibility for legacy data.

Changes:

• Updates clock API, service, controller, route, WebSocket, and tests to use user-scoped clock sessions.
• Removes Team column/selection from personal timesheet row rendering and manual entry creation.
• Updates frontend clock consumers and e2e tests to call clock endpoints without teamId.
