Bridge status indicator now carries an explicit status instead of a boolean

What

• The status/footer line's bridge indicator used to render only when a column-width/boolean gate was true, passing just a bridgeSelected flag. Now it always computes a status value and renders the bridge chip whenever that status isn't null, passing a status field to the bridge component instead of gating on column width.
• As part of this, the status-line render function no longer destructures ideSelection or mcpClients from its props, and no longer computes or renders an IDE-colored badge.

Why This makes the bridge indicator reflect a real connection status rather than a simple on/off flag, though it also means the footer no longer shows a separate IDE badge.
