Feat/dashboard layout

[austinpickett]

What does this PR do?

Improves the Hermes web dashboard (hermes-agent/web/) shell and key flows: clearer sidebar (gateway vs agent, System block, version + org in the footer), a single home on Sessions (with alerts, system-action log, platforms, and recent sessions), full-width main content, header toolbars on Logs and Analytics, delete/clear confirmations (Cron, Sessions, env keys) via a small reusable hook + dialog, and i18n updates. No change to how dashboard plugins are loaded—the example plugin still appears as the dynamic /example tab when the API serves it.

Changes Made

• hermes-agent/web/src/App.tsx: Default route → /sessions; remove Status nav; full-width main; System section + sidebar link targets; navigate after system actions to /sessions.
• hermes-agent/web/src/components/SidebarStatusStrip.tsx, SidebarFooter.tsx: Footer version + Nous link; gateway/session copy; merge into System; Link to /sessions.
• hermes-agent/web/src/pages/SessionsPage.tsx: Hub for former Status content (alerts, action log, PlatformsCard, recent sessions) + session list; DeleteConfirmDialog + useConfirmDelete.
• hermes-agent/web/src/components/PlatformsCard.tsx: Extracted connected-platforms card.
• Removed hermes-agent/web/src/pages/StatusPage.tsx (behavior relocated as above).
• hermes-agent/web/src/i18n/*: app.nav / gatewayStrip / activeSessionsLabel / gatewayStatusLabel / env clear strings / nav cleanup; zh parity.
• hermes-agent/web/src/lib/resolve-page-title.ts: / and titles align with Sessions-first nav.
• hermes-agent/web/src/hooks/useConfirmDelete.ts, components/DeleteConfirmDialog.tsx: Shared delete confirmation.
• hermes-agent/web/src/pages/CronPage.tsx: Delete confirm; loadJobs useCallback where needed.
• hermes-agent/web/src/pages/EnvPage.tsx: Clear-key confirm + clearDialogOpen on rows.
• hermes-agent/web/src/pages/LogsPage.tsx: fetchLogs before header effect; auto-refresh + refresh in setEnd; setAfterTitle badge.
• hermes-agent/web/src/pages/AnalyticsPage.tsx: Period + refresh in header; setAfterTitle period badge.
• hermes-agent/web/src/pages/AnalyticsPage.tsx / LogsPage: usePageHeader (setEnd / setAfterTitle).

How to Test

1. From hermes-agent/web: pnpm dev (with the gateway/web API proxying so /api/* and plugins work as usual).
2. Nav / home: Open / → redirects to Sessions; confirm sidebar (System block, gateway lines, footer version + Nous link).
3. Sessions: Alerts/platforms/recent + list; delete session → confirm dialog; cancel vs confirm.
4. Cron / Keys: Delete cron job and clear an env key → confirm dialogs; cancel leaves data.
5. Logs: Auto-refresh + Refresh in the header; filters stay in the page.
6. Analytics: Period chips + Refresh in the header; data still loads on period change.
7. Plugin (optional): With server discovering plugins/example-dashboard, open /example and confirm Example tab.
