feat(ui): add color accents across the connection manager

- Default protocol color strips on all host cards (wraith-blue for SSH, purple for RDP)
- Deterministic tag colors from 8-color palette (teal, amber, violet, rose, emerald, sky, orange, indigo)
- Last-connected recency coloring (green=today, amber=this week, gray=older)
- Section header dots (wraith-400 for Recent, gray for All Hosts)
- Active nav link highlighting (wraith-400)
- Group headers get subtle wraith-500 left border accent
- Tree host dots default to protocol color instead of gray
- Fixed rogue modal using hardcoded #1a1a2e/#e94560 — now uses design system
- Fixed sky-600 save buttons → wraith-600 for brand consistency
- Credential type badges: SSH Key=wraith, Password=amber (was purple/blue)
- Colored tags in right sidebar detail panel
