vscode: migrate Status view from sidebar to Codev panel tab

[amrmelsayed]

Problem

The Status view (packages/vscode/src/views/status.ts) lives in the Codev sidebar today, occupying a row for what's essentially a single piece of connection state (connected / disconnected to Tower) plus a codev.reconnect action. The sidebar's row-per-view real estate isn't justified by the content. Moving Status to the panel groups it with the other secondary surfaces (Recently Closed, Team) and frees a sidebar slot.

The status-bar option (where this kind of state typically lives) was considered and explicitly deferred ("Not now") in favor of the panel placement; this issue documents that decision.

Proposed behavior

Migrate the existing codev.status view from the codev (sidebar) container to the new codevPanel (panel) container introduced in #812. No data, rendering, or interaction changes — same provider, same row(s), same codev.reconnect view-title action.

Implementation

1. In packages/vscode/package.json, move the codev.status view entry from contributes.views.codev to contributes.views.codevPanel.
2. codev.reconnect in view/title is keyed by view == codev.status — no when-clause change needed.
3. Smoke-test that the connection-state row updates on connect / disconnect events after the move.

Acceptance criteria

• codev.status registered under viewsContainers.panel.codevPanel, not under activitybar.codev.
• Status tab no longer appears in the Codev sidebar.
• Connection-state row appears in the Codev panel area, fully functional.
• codev.reconnect action still fires correctly from the panel-side view title.
• No regression to other Codev views (sidebar or panel).

Depends on

• vscode: introduce a Codev panel tab (bottom-area view container) to relieve sidebar overload #812 — Codev panel container scaffolding must land first.

Out of scope

• Moving the connection-state indicator to the status bar (intentionally deferred — see vscode: notification hygiene refactor — centralize connection guard, demote success toasts, add Output channel #794, which still earmarks a status-bar disconnect indicator as part of the broader notification refactor; the panel-side row coexists with that).
• Expanding Status content (e.g. Tower uptime, workspace count). Could be a follow-up if the panel-side row feels too thin.
