fix(desktop): scope messaging sidebar sessions to active profile

[hashbender]

What does this PR do?

The messaging sidebar (Telegram, Discord, Slack, etc.) always fetched sessions with profile='all', ignoring the active profile switcher. When a user switched profiles in the desktop app, local recents updated correctly, but the messaging platform sections continued showing chats from every profile — so the Telegram sidebar appeared "stuck" on a single profile's chats.

This fix passes profileScope to listAllProfileSessions in both refreshMessagingSessions and loadMoreMessagingForPlatform, matching the existing pattern used by refreshSessions for local recents.

• ✨ New feature (non-breaking change that adds functionality)
• 🔒 Security fix

• ✅ Tests (adding or improving test coverage)
• ♻️ Refactor (no behavior change)
• 🎯 New skill (bundled or hub)

Changes Made

• apps/desktop/src/app/session/hooks/use-session-list-actions.ts: Changed refreshMessagingSessions and loadMoreMessagingForPlatform to scope the session fetch to the active profileScope instead of hardcoding 'all'. Added profileScope to both useCallback dependency arrays so they re-fetch when the user switches profiles.
• apps/desktop/src/hermes.test.ts: Added test verifying listAllProfileSessions forwards a specific profile name in the API request path.

How to Test

1. Configure Hermes with multiple profiles (e.g., local, remote, default), each with Telegram enabled
2. Open the desktop app and verify the Telegram sidebar shows chats from all profiles initially
3. Switch to a specific profile (e.g., local) in the app's profile switcher
4. The Telegram sidebar should now show only chats from the local profile
5. Switch to remote — the sidebar should update to show only remote profile's Telegram chats
6. Switch back to "All profiles" — the sidebar should show chats from all profiles again
7. Should pass: npx vitest run apps/desktop/src/hermes.test.ts --reporter=verbose

Screenshots / Logs

N/A — the fix is a 3-line behavioral change in session fetch scope (plus comments and dependency arrays). The listAllProfileSessions API already supports per-profile filtering; the call sites just weren't using it.
